[PATCH 21/30] send-pull-request: remove local mta support

[Saul Wold <sgw@linux.intel.com>]

From: Darren Hart <dvhart@linux.intel.com>

There is no real value in supporting sendmail directly when git
can be configured to use it. The script used to generate the
pull request mails relies heavily on git, so doing so here does
not impose any additional dependencies and it greatly reduces the
complexity of this script.
