As pointed out by Kai, I can avoid one level of shell wrapping. Mock
is already running this via "/bin/sh -c" (function doshell in
/usr/lib/python2.7/site-packages/mockbuild/util.py currently).

Change the "make shell" command to invoke a shell as the "mockbuild"
user and starting in ~mockbuild. This is typically what you want when
you enter the build environment.
Add a new target, "rootshell", which gives the old behavior, a root
shell starting at /.
