bsd-user/bsdload.c: Remove write-only id_change variable

Browse Source 
On OpenBSD the compiler complains:
bsd-user/bsdload.c:54:17: warning: variable 'id_change' set but not used [-Wunused-but-set-variable]

This is dead code that was originally copied from linux-user.
We fixed this in linux-user in commit 331c23b5ca in 2011;
delete the useless code from bsd-user too.
