package: fix distcheck

Bison emits strings to translate in the generated code, for builtin
tokens.  So they appear only in generated parsers, which are not
shipped, so they are not in the src tree, so we cannot use them in our
POTFILE.

Except src/parse-gram.c, which is in the source tree.  And even in the
git repo.  But to avoid useless diffs in the repo, we do not keep the
src/parse-gram.c _with_ the #lines.  This is done in a dist-hook which
regenerates src/parse-gram.c when we run "make dist".

Unfortunately, then, update-po traverses the whole tree and sees that
the location of the strings to translate in src/parse-gram.c have
changed, so the bison.pot is to be updated.  And that is not possible
in the "make dist" which is run within "make distcheck"
(not the one preparing the dist for distcheck, the one run by
distcheck to check that a distributed tarball can build a tarball)
because then the src tree is read-only.

So let's not put src/parse-gram.c in the POTFILE, and expose these
strings to gettextize by hand.

* src/i18n-strings.c: New.
* po/POTFILES.in: Add it, and remove src/parse-gram.c.
