Replace patched harfbuzz.pc

Wen HarfBuzz-enabled FreeType is built, HarfBuzz gets located via its
pc-file which references FreeType’s pc-file. If there’s no such pc-file
in the search path it errors out.
Add the previously built HarfBuzz-less FreeType’s pc-file to the search
path to avoid this. It has no ill effect on the static lib we build.
