Solaris support in grub_find_zpool_from_dir().  Thanks
	Seth Goldberg for referring to getextmntent() facility.
	
	* configure.ac: Check for getextmntent(), `sys/mnttab.h' and
	`sys/mkdev.h'.
	* grub-core/kern/emu/misc.c [HAVE_SYS_MNTTAB_H]: Include
	`<sys/mnttab.h>'.
	[HAVE_SYS_MKDEV_H]: Include `<sys/mkdev.h>'.
	[HAVE_GETEXTMNTENT] (grub_find_zpool_from_dir): Add getextmntent()
	method for finding zpool name.
