syscalls/setregid02: Fix retrieving a group of user "nobody"
In setup this test sets UID and GID of the user "nobody". Then
it expects that user "nobody" is in group "nobody" and tries to
retrive a structure for group "nobody" using getgrnam(). However
some Linux distributions use group "nogroup" for user "nobody".
Thus it's necessary to retrieve a group of user "nobody" not by
hardcoded name but by its GID. It's necessary because group
"nobody" may not exist.
I've replaced a variable "nobody" by more generic "ltpgroup".
Then I've created 2 functions get_group_by_name and
get_group_by_gid which are used instead of GET_GID macros.
On my test system I have user "nobody" in group "nogroup". So
I've got this error messages for this test:
----------->8----------
setregid02.c:160: getgrnam("nobody") failed: errno=SUCCESS(0): Success
setregid02.c:160: Remaining cases broken
