system: Don't emit a GRUB 'search' command when passed a GRUB file name.
Reported by Tomáš Čech <tcech@suse.com> at <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20067#26>. * gnu/system/grub.scm (grub-root-search): Don't emit anything when FILE is a string that does not denote an absolute file name.
