luci.mk: fix compatibility with GNU Make 4.2

Browse Source 
GNU Make version 4.2 chokes on `#` characters embedded in variable
substitutions, leading to the following error:

    ../../luci.mk:114: *** unterminated call to function 'if': missing ')'.  Stop.

Avoid this problem by replacing variable substitutions with Git branch
format arguments.
