sapi/*/Makefile.frag: install programs built with libtool, with libtool

When installing executables that were built using libtool, we are
supposed to use

  $ libtool --mode-install <install-command>

rather than the bare <install-command>. This is discussed ever so
briefly in the "Installing executables" section of the GNU libtool
documentation:

  https://www.gnu.org/software/libtool/manual/libtool.html

So far this has not caused a problem with GNU libtool on the platforms
that PHP supports, but there is an alternate libtool implementation
called slibtool that stores wrappers at the locations where PHP is
expecting the true executables to live. As a result, the wrappers (and
not the executables) are installed when slibtool is used to build PHP.

This is fixed by replacing,

  $(INSTALL)

with

  $(LIBTOOL) --mode=install $(INSTALL)

in the install-foo rules for the executables that are built with
libtool.

Closes GH-13674
