Call modprobe with absolute path

Some sudo configurations may not include /sbin in the PATH.
libzfs_load_module() currently does not call modprobe with an absolute path, so
it may fail under such configurations if called under sudo.  This change adds
the absolute path to modprobe so we no longer rely on how PATH is set.
