[PATCH] email-sh-functions: add local variables to parse_prj_config

[Artem Bityutskiy]

From: Jacob Keller <jacob.e.keller at intel.com>

Rather than assuming that the $cfgfile and $prj will be correctly defined, use
the passed parameters. Use local to create local variables to use, just like
in the regular config parsing.
