kernel: add do_getpgid() helper; remove internal call to sys_getpgid()
Using the do_getpgid() helper removes an in-kernel call to the
sys_getpgid() syscall.
This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see
