Revert "disable seccomp"
Confirmed that libminijail checks for seccomp support in
kernel before attempting to apply a filter.
This reverts commit 1ab2f2d0a6208ec9b6bb7e8b130efa9b70737f98.

mediaex: apply seccomp filter
We can safely reduce the number of accessible system calls from ~250
down to ~30.
This commit adds a seccomp filter for arm/arm64 devices. Mediaextractor
runs as a 32 bit process so the same filter is used for both arm and
arm64 devices. The filter is arranged by frequency of the systemcall to
provide the best performance.
Most system calls are whitelisted without argument inspection. The
exception is the socket syscall where the first argument is checked to
ensure only domain=AF_LOCAL sockets are allowed - used for logging.
Vendor additions may be appended to the default filter by creating
mediaextractor-seccomp.policy file and pointing BOARD_SECCOMP_POLICY
to the directory where it resides. For example:
create: device/<oem>/<target>/seccomp/mediaextractor-seccomp.policy
with the necessary syscalls. set:
BOARD_SECCOMP_POLICY=device/<oem>/<target>/seccomp
in the device's BoardConfig.mk

Extractor service
Run extractors in a separate process. Currently all data is copied through a
binder transaction, and WVMExtractor is still run in the mediaserver process.
