[RFA] bsd-kvm.c: get exec file name

["Nathan J. Williams" <nathanw@wasabisystems.com>]

This changes bsd_kvm_open() to pass the exec file in use to
kvm_openfiles() rather than NULL, which improves results when you run
"gdb /some/other/kernel" "target kvm kernel.core".

OK to commit?

	* bsd-kvm.c: Include "gdbcore.h"
	(bsd_kvm_open): Delete variable 'execfile'. Pass return value of 
	get_exec_file() to kvm_openfiles().
