fontconfig: upgrade to 2.11.1

fontconfig: upgrade to 2.11.1

Removed the following patch(es):
 * sysroot-arg.patch (changes included in release)

Correct the fccache.c license checksum and the line numbers because the
license snippet has moved and, also, at the previous upgrade the lines
were wrong (shifted a couple of lines).
