Our functions that query /proc/pid/ support using pid==0 to mean
self. get_process_id also seemed to support that, but it was not implemented
correctly: the result should be in *uid, not returned, and also it gave
completely bogus result when called from get_process_gid(). But afaict,
get_process_{uid,gid} were never called with pid==0, so it's not an actual
bug. Remove the broken code to avoid confusion.

- if (pid == 0)
- return getuid();

p = procfs_file_alloca(pid, "status");
f = fopen(p, "re");
if (!f) {
