[PATCH RESEND v2] make: add install-stripped target

[Bagas Sanjaya <bagasdotme@gmail.com>]

Add the target that install Git with stripped executables.

install and install-stripped share the almost-same recipe, with the
difference only on extra arguments to $(INSTALL). In order for this to
work properly, installing all programs ($(ALL_PROGRAMS) and
$(install_bindir_programs)) must be splitted into separate portions for
compiled programs and scripts. For the former, add $(INSTALL_OPTS) and
for the latter, don't add anything.

$(INSTALL_OPTS) contains stripping options that are passed from
install-stripped.

 Changes from v1:
 - Share recipes between install-stripped and install targets (suggested
   by Junio)
 - Don't delete 'strip' target. There may exist scripts that depend on
   that target. Once this patch is integrated, deprecation notice can
   be displayed when running the target, but it is done in separate
   patch.
