In cpu_fork() set tf_npc as well in case a signal is taken in child_return()
...
which will cause the values of tf_pc and tf_npc set here in cpu_fork()
to be restored and used to return to user space from sigreturn() eventually
(before that the tf_pc and tf_npc set in sendsig() will be used in
proc_trampoline()).
Also, the fork system call never uses the SYSCALL_G2RFLAG shortcut, so drop
the code handling that.

Change interface between cpu_fork() and proc_trampoline() so that `tf_pc'
...
(instead of `tf_npc') contains the user-space return address. This ensures
entering the signal trampoline code correctly in case we take handled
signal during child_return().

add -Os to COPTS after <bsd.prog.mk> is pulled in rather than adding

it in CFLAGS beforehand, as a user's mk.conf COPTS+=-O2 results in
boot files that are too large.
