relocate.cc: Introduce new command set?.

Contrary to set, set? won't override environment variables that are
already set.

We need this for reproducable builds, in particular with gub: The standard
fontconfig setup includes font files like ~/.fonts or /usr/share, which
obviously must not be used. Up to now, the fontconfig.reloc file in gub
uses the set relocation command, which doesn't allow gub to replace the
fontconfig configuration file with a temporary alternative while building
test files or documentation. Future changes in gub will use set? instead.
