pkg-mgr-commands.tex: Drop CONF_LIBDIR* and DEFAULT_ABI

The CONF_LIBDIR variable was used exclusively in the 2004.3 profile
(i.e. it was no longer defined in 2005.0). Portage support for
CONF_LIBDIR was added by this commit:
https://gitweb.gentoo.org/archive/proj/portage-cvs.git/commit/?id=ecc2faaa00b1e6250129267ba873bedd2121eac5
Note that neither the ABI nor the LIBDIR_${ABI} variable existed at
the time.

The CONF_LIBDIR_OVERRIDE and DEFAULT_ABI variables were never
implemented in the dolib* and einstall commands in Portage.

With the three variables dropped, the algorithm is identical to the
logic used for get_libdir(). Therefore drop alg:ebuild-libdir and
refer to alg:get-libdir instead.
