Add pkgconfig files for provided libraries

* .gitignore: Add .pc files as they are generated by autoconf.
* configure.ac: Generate .pc files for libpam, libpam_misc and libpamc.
* libpam/Makefile.am: Install pam.pc.
* libpam/pam.pc.in: New file.
* libpam_misc/Makefile.am: Install pam_misc.pc
* libpam_misc/pam_misc.pc.in: New file.
* libpamc/Makefile.am: Install pamc.pc

This allow applications and PAM modules to automatically find libpam,
libpam_misc and libpamc if they are installed instead of having to
manually search for them.
