linux-user: Populate more bits in mmap_flags_tbl
Fix translation of TARGET_MAP_SHARED and TARGET_MAP_PRIVATE,
which are types not single bits. Add TARGET_MAP_SHARED_VALIDATE,
TARGET_MAP_SYNC, TARGET_MAP_NONBLOCK, TARGET_MAP_POPULATE,
TARGET_MAP_FIXED_NOREPLACE, and TARGET_MAP_UNINITIALIZED.
Update strace to match.
