getlogin_r: return early when linux sentinel value is set
When there is no login uid Linux sets /proc/self/loginid to the sentinel value of, (uid_t) -1. If this is set we can return early and avoid needlessly looking up the sentinel value in any configured nss databases. Checked on aarch64-linux-gnu. * sysdeps/unix/sysv/linux/getlogin_r.c (__getlogin_r_loginuid): Return early when linux sentinel value is set.
