target/xtensa: linux-user: fix sysv IPC structures
- make target_ipc_perm fields match kernel definitions for xtensa;
- add target_semid64_ds with proper order of times and reserved fields
for little/big endian specific for xtensa;
- add missing reserved fields after time fields to the target_shmid_ds;
- fix types of shm_cpid, shm_lpid and shm_nattch fields of
target_shmid_ds to match kernel definitions for xtensa.
These changes fix guest ipcs output and fix glibc testsuite tests
sysvipc/test-sysvsem and sysvipc/test-sysvshm.
