FcCharSetFreezeOrig(), FcCharSetFindFrozen(): use all buckets of freezer->orig_hash_table

As written at:

  https://lists.freedesktop.org/archives/fontconfig/2017-June/005929.html

I think FcCharSetFreezeOrig() and FcCharSetFindFrozen() should use the %
operator instead of & when computing the bucket index for
freezer->orig_hash_table, otherwise at most 8 buckets among the 67
available (FC_CHAR_SET_HASH_SIZE) are used.

Another way would be to change FC_CHAR_SET_HASH_SIZE to be of the form
2**n -1 (i.e., a power of two minus one). In such a case, the & and %
operators would be equivalent.
