[BusyBox] [PATCH] id minor bugfix and code clean up for my_getpwuid and my_getgrgid

Hi, to all
This patch fixes a corner case in which id applet doesn't produce the same output
as GNU id:

user: pippo, uid 502, gid 504,  default group pippo:504 in /etc/group deleted

./busybox id -g pippo
id: unknown gid 504
GNU:
id -g pippo
504

The patch also cleans up code formatting and removes
some not needed includes.
