cfgPath: fix path to cfg file for *_DIR_EXTRA

When eups sucks a file in, e.g.:
  eups declare python system -r none -m none -L python.cfg
it puts it directly in $PYTHON_DIR_EXTRA, not in an additional
'ups' subdirectory.
add -ftemplate-depth-256 to CXXFLAGS for clang

Use of boost requires a deeper template depth than provided by
default for clang++ on MacOS 10.9.
Merge branch 'tickets/3076': Update sconsUtils for MacOS 10.9
We need to pass EUPS_SHELL as eups commands run from within scons now rely on it
