Update Android FreeType version.
Update FreeType to a newer version. Because this caused issues in
finding the correct ftoptions.h and ftmodule.h [1], be sure to state
the ones we want explicitly.
This also add gzip.c which is needed for WOFF support [2].
[1] FreeType "Simplify header file hierarchy."
fae382076409db198dfbff36ac4cbb97b05b30a1
[2] FreeType "[gzip] New function `FT_Gzip_Uncompress'."
