Change disables loading of res_hep.so in default installation. Loading
res_hep has a performance impact whether it's used or not. This disables
loading of it in sample config files.

The sample modules.conf explicitly loaded res_musiconhold.so. This is
redundent as autoload=yes is already set. It causes warnings if
res_musiconhold.so was not installed and results in an unexpected load
if the admin disables autoload without remembering to remove the
res_musiconhold load statement.
Also remove reference to unknown module pbx_gtkconsole.
