hal: fix libadm.so right path in LE platform

/usr/lib64 not exists in LE, ADM_LIBRARY_PATH
change to /usr/lib.

if libadm.so unavailable, caused below chains:
1. struct stream_in::real_time will be false
2. will not attach flag PCM_MMAP while pcm_open

if we now use ULL_NOIRQ(FE: MultiMedia8) device to
open capture, mmap func will not called, and
pcm_prepare failed.
