The proposals bot run on a tree that is in detached state. Current
git review fails to push from this any changes.
Create instead directly a branch and work on that.
This is the same change as done for other proposal jobs in
I487337cb1def5f5995d776c831ea61b658652677.

Using the construct of x$var != x is unnecessary, and has been
unnecessary for quite some time. We trust our shell, so switch to
using test -n.

Add a job that will propose a change (or update a change) to
normalize projects.yaml, and run it once daily. Normalization,
in this case, chiefly means removing un-used upstream lines
from projects.yaml (but will also catch minor YAML errors and
line wrapping).
Also simplify the proposal node regex.
