Avoid linking problem in sys_reset_uid_gid
* lib/system.h (sys_reset_uid_gid) [!MSDOS]: On failure, instead
of invoking FATAL_ERROR set errno and return the name of the
syscall that failed, so that the caller can decide what to do.
This avoids some GNU Tar linking problems on compilers that do not
inline this function. All callers changed.
