Fix score evaluation for multiple values in properties

Sometimes fonts has multiple values in family and sub-family in order to unify
other variants into one. they basically make difference in sub-family though,
they also still have standalone family and sub-family. in that case, sub-family is
likely to be Regular.

fontconfig couldn't recognize the difference between :family=Foo:style=Regular
and :family=Foo Caption:style=Regular for example because fontconfig didn't
give different score on matching result for the position of multiple values in
a cache.
Thus, when querying a font like :family=Foo:style=Regular may results
:family=Foo Caption:style=Regular. (see the test case for more details)

To fix this situation, giving different score according to the position
of multiple values in a cache as well as the position of multiple values
in a query.
