build: use only one m4/ directory

* Makefile.am (ACLOCAL_AMFLAGS): Specify only one include dir: m4.
* bootstrap: Tell gnulib-tool to put .m4 files in m4/, not gnulib/m4.
* autogen.sh: Move autoreconf from here into...
* bootstrap: ...here, so that it is run only when gnulib-tool is.
Also, tell it to skip the usual autopoint and libtoolize runs.
* m4/.gitignore: Update.
