Ignore wipe operation on non-block devices.
The implementation of make_ext4fs() calls make_ext4fs_internal() by
forcing the |wipe| parameter to true, which is problematic when the
library is used within the emulator (the wipe operation will always
fail on non-Linux platforms).
This patch does the following:
- Add a 'is_block_device_fd()' function to check that a file descriptor
points to a real block device.
- Modify the implementation of wipe_block_device() uses it to return
silently when trying to wipe a non-block-device file.
- Add a WIPE_IS_SUPPORTED flag in wipe.h that indicates whether
block device wiping is supported on the current platform
(for now, this is only the case on Linux).

Make a failure of the BLKDISCARD ioctl non-fatal.
Failure to erase the partition before making a new filesystem
should not be fatal, especially since this is called from recovery,
and if make_ext4fs() dies, recovery dies.

ext4_utils: Add support for wipe option, and wipe by default in recovery
Adds a -w option to make_ext4fs, which will attempt to use the
BLKSECDISCARD ioctl to erase the partition in order to avoid
leaving old data where it could be recovered, and to improve
wear levelling after a reformat.
Also causes factory reset through recovery to do a wipe.
