autofs-5.0.7 - add std vars to program map invocation

From: Ian Kent <ikent@redhat.com>

Program maps currently don't have the standard macro variables set
in the environemt when they run.

Also, program maps aren't necessarily executed within a shell so
setting the standard variables in the environment needs to be done
the same way it's done by the Sun map parser.
