BACKPORT: libselinux: procattr: return einval for <= 0 pid args.

getpidcon documentation does not specify that a pid of 0 refers to the
current process, and getcon exists specifically to provide this
functionality, and getpidcon(getpid()) would provide it as well.
Disallow pid values <= 0 that may lead to unintended behavior in
userspace object managers.
