[Fontconfig] Tiny improvement for fontconfig

[Michail Vidiassov]

Dear Keith,

src/fcfreetype.c contains the following code:
---------------------------------------------
    /*
     * Skip over PCF fonts that have no encoded characters; they're
     * usually just Unicode fonts transcoded to some legacy encoding
     */
    if (FcCharSetCount (cs) == 0)
    {
        if (!strcmp(FT_MODULE_CLASS(&face->driver->root)->module_name, "pcf"))
            goto bail2;
    }
---------------------------------------------

Why BDF fonts are not skipped over in the same way as PCF ones?


                  Sincerely, Michail
