[Buildroot] [PATCH] ejabberd: Call check-erlang-lib script directly from its location

[Johan Oudinet <johan.oudinet@gmail.com>]

Avoid installing check-erlang-lib in the directory where the tarball is
extracted. Instead, use an absolute path to its actual location, i.e.:
$(TOPDIR)/$(EJABBERD_PKGDIR)/check-erlang-lib
