Stop supporting non-POSIX getpwuid_r, getgrgid_r

Browse Source 
Bug 13403 introduced support for the non-POSIX variants of these APIs
found on a system called "DG/UX".  Meanwhile, the complicated checks
here are breaking cross-builds on systems that we actually care about.

Remove the complicated checks and replace them with AC_CHECK_FUNCS.
Remove the resulting dead code from a couple of .c files.
