Updated to libXfont 1.5.1

In addition to some other changes, the following CVEs have been
fixed:
bdfReadProperties: property count needs range check [CVE-2015-1802]
bdfReadCharacters: bailout if a char's bitmap cannot be read [CVE-2015-1803]
bdfReadCharacters: ensure metrics fit into xCharInfo struct [CVE-2015-1804]
