[LTP] [PATCH] setregid: use common user and group names.

[Cyril Hrubis]

Hi!
FIY this seems cause failures on Debian 9 where I do get failures:

setregid03    1  TBROK  :  setregid03.c:198: nobody must be a valid group
setregid03    2  TBROK  :  setregid03.c:198: Remaining cases broken

setregid04    1  TBROK  :  setregid04.c:126: Couldn't find the `nobody' group
setregid04    2  TBROK  :  setregid04.c:126: Remaining cases broken

I guess that we need a fallback if nobody group does not exist.
