[woff2] Remove sfnt size guess check 

In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value
is now just a hint and a conforming implementation must not reject
otherwise valid data if the `totalSfntSize` turns out not to be exact.

* src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed
woff2 data would fit in the sfnt size guess.

Fixes: #1235
