unix: add *at functions (POSIX.1-2008) on FreeBSD 

Add the Faccessat, Fchmodat, Fchownat, Linkat, Mkdirat, Readlinkat,
Renameat, Symlinkat and Unlinkat functions (to conform to POSIX.1-2008)
and also add the missing AT_* constants.

Generated on FreeBSD 10.11-RELEASE for freebsd/amd64 and freebsd/386.
