lib: check ‘install file dir/’

* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Check that the
system install program works when the destination name has a
trailing slash.  This helped catch problems in an experimental and
never-published version of GNU Coreutils, and is a good thing to
check in general.
