rpm macros: install macros file

For now, only %postgresql_major macro is defined.

* .gitignore: New file.
* Makefile.am: Include new makefile snippet.
* configure.ac: Define rpm macros dir.  This still needs to be
fixed for SCLs (or defined explicitly during build), or removed
because we don't build external plugins yet?  Also bump package
major version because this requires non-trivial update in spec
files.
* lib/rpm/Makefile.inc: New file.
* lib/rpm/macros.d/macros.in: New template file.
