Subject: build: Use a 'guile' executable that doesn't warn about locales.

This gets rid of:

  guile: warning: failed to install locale

when running the 'guix' command on a foreign distro where 'GUIX_LOCPATH'
isn't set.

* Makefile.am (pkglibexec_PROGRAMS, guile_SOURCES, guile_LDADD)
(guile_CFLAGS): New variables.
(install-exec-hook): New target.
(AUX_FILES): Remove 'guile-launcher.c'.
* configure.ac: Use 'GUILE_FLAGS'.
