If statements to getresuid() and getresgid() in setuid.c shouldn't have an extra space.

In setuid.c:

src/lib/process/setuid.c:  if (getresuid(&ruid, &euid, &suid) != 0 ) {
src/lib/process/setuid.c:  if (getresgid(&rgid, &egid, &sgid) != 0 ) {

These if statements to getresuid() and getresgid() shouldn't have an extra space.
