Revert "Make font-based unit test depend on instdir fonts"

The following build:

 $ make clean && make gb_CppunitTest_sc_ucalc
 [...]
 $ cd sc
 $ make gb_CppunitTest_sc_ucalc

triggers:

sc/CppunitTest_sc_subsequent_filters_test.mk:133:
   *** Missing font filelist -> run make more_fonts extras.

This didn't help the general Win32 font build problem AFAIK. There
were additional patches to the way Windows loads the LO provided
fonts, so just revert this.

This reverts commit 368c996b24.
