There are essentially two possible implementations for Setuid/Setgid on Linux, either using SYS_SETUID32/SYS_SETGID32 or SYS_SETUID/SYS_SETGID, depending on the architecture (see golang/go#1435 for why Setuid/Setgid aren currently implemented for Linux neither in syscall nor in golang.org/x/sys/unix). Reduce duplication by merging the currently implemented variants and adjusting the build tags accordingly. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
