Dmitry V. Levin 3a15bc8adf tests: fix uid tests on big endian architectures
* tests/uid.c (main): Ignore uids returned by getresuid to avoid
16bit vs 32bit issues on big endian architectures.
Change real UID instead of effective UID in setresuid test.
* tests/uid16.c (main): Likewise.
* tests/uid32.c (main): Change real UID instead of effective UID
in setresuid test to match uid.c
* tests/uid.awk: Update setresuid regexp.
