umpf: add new flag to insert 'Upstream-Status: Pending' lines to all …

…patches

Starting with the mickledore release, the upstream status is required
for all patches in Yocto.
Add a new flag "upstreamstatus" to handle this. If set to "insert",
"Upstream-Status: Pending" is added to the commit message of all patches
during "umpf tag".
