build: improve GIT_CONF_SUBST signature

Now, in configure.ac, a call like:

    GIT_CONF_SUBST([FOO])

will be considered equivalent to:

    GIT_CONF_SUBST([FOO], [$FOO])

This is mostly a preparatory refactoring in view of future changes.
No semantic change to the generated configure or config.mak.auto is
intended.
