powerpc: Fix lwsync patching code on 64bit 

do_lwsync_fixups doesn't work on 64bit, we end up writing lwsyncs to the
wrong addresses:

0:mon> di c0000001000bfacc
c0000001000bfacc  7c2004ac      lwsync

Since the lwsync section has negative offsets we need to use a signed int
pointer so we sign extend the value.
