[LTP] [PATCH v2] setpgid02: use 1 instead of getpgid(1)

[Edward Liaw via ltp <ltp@lists.linux.it>]

On Android, init does not setpgid, so getpgid(1) returns 0 and the third
case of setting pgid to a different session's process group does not
behave as expected: setpgid treats 0 as setting the pgid to the pid.

Instead, replace SAFE_GETPGID(1) with the expected value of 1.
