ftgl: Fix builds with freetype 2.13.3

Based on research into this issue, freetype 2.13.3 changed some return
types that caused current (modern?) builds to fail as seen in the linked
ticket.

A patch was applied with frankheckenbach/ftgl#20 that appears to fix
this, but the repo owner has not indicated a plan to cut a new release
with this and other fixes since v2.4.0.

In addition to the patch files that were previously present, I have
applied all other patches from v2.4.0 to current HEAD. This involved
removing the existing patch files, but those changes have been fully
incorporated.

Builds with +doc and +universal variants worked fine and I have tested
a downstream port (gource) with this on an affected system.
