INSTALL: convert to '' quoting, drop blank line at end

This is allowed by recent GNU Coding Standards changes, and mirrors recent gnulib changes: https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00267.html https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00298.html I've confirmed that after these changes, the INSTALL generated and installed by autoconf matches the INSTALL.ISO in gnulib. * Makefile.am ($(srcdir)/INSTALL): Match gnulib INSTALL.ISO.
