[kteam-tools][PATCH 3/4] git-build-kernel: support SOURCE_PACKAGE_CHROOT=series via debian.env

[Kamal Mostafa]

When building a source package via the "git push commit-ish:source"
method...

If debian/debian.env contains a "SOURCE_PACKAGE_CHROOT=series" line
(where series is a distro series like 'xenial') then git-build-kernel
will build the source package in a chroot of that specified series.

If no SOURCE_PACKAGE_CHROOT line exists, then git-build-kernel will use
a chroot of the series indicated by debian/changelog.

The SOURCE_PACKAGE_CHROOT feature applies only to *source* package
builds; binary packages are always built in a chroot of the series
indicated by debian/changelog.
