libdwfl: Fix memory leak in link_map.c dwfl_link_map_report.
The phdrs buffer could come from the core file or through the executable.
dwfl_link_map_report would leak the buffer if it came from the executable.

Trust AC_SYS_LARGEFILE to provide large file support
AC_SYS_LARGEFILE defines _FILE_OFFSET_BITS in config.h if needed for
LFS, and this automatically maps things like open to open64. But quite
a few places used explicit 64-bit names, which won't work on platforms
like FreeBSD where off_t is always 64-bit and there are no foo64 names.
It's better to just trust that AC_SYS_LARGEFILE is doing it correctly.
But we can verify this too, as some file could easily forget to include
config.h. The new tests/run-lfs-symbols.sh checks all build targets
against lfs-symbols (taken from lintian) to make sure everything was
implicitly mapped to 64-bit variants when _FILE_OFFSET_BITS is set.

Therefore elfutils now incorrectly matches on-disk file without build-id to an
in-core (in-memory) file with build-id.
In fact due to its known FIXME:
This verification gives false positive if in-core ELF had
build-id but on-disk ELF does not have any. But we cannot
reliably find ELF header and/or the ELF build id just from
the link map (and checking core segments is also not
reliable). */
So it probably should not be so ignorable as I did, one may want to analyze
build-id core files on CentOS-5, not sure. In fact it can be fixed, when we
find in dwfl_segment_report_module a module with build-id with conflicts in
its address range with existing non-build-id dwfl_link_map_report module we
should prefer the build-id module instead.
The problem is that once Dwfl_Module is added to Dwfl it cannot be easily
removed.
Originally elfutils called dwfl_segment_report_module first and then
dwfl_link_map_report.
Currently the order is dwfl_link_map_report and then
dwfl_segment_report_module only for modules missing from dwfl_link_map_report.
Patch below unfortunately needs bidirectional negotiation between the two
functions, therefore dwfl_link_map_report now no longer adds Dwfl_Modules to
Dwfl but it only stores information about them to r_debug_info_module.
This information is filtered then by dwfl_segment_report_module and only
filtered r_debug_info_module entries get finally added to Dwfl
(in dwfl_core_file_report).
NT_FILE would make all this magic easy but it is true that on CentOS-5 it
definitely does not exist.
