remove fix_rcc_determinism.patch
Fixed upstream in https://bugreports.qt.io/browse/QTBUG-62511

remove freetype_back_compat.patch
By the time we ship a release with Qt 5.12, we'll certainly no-longer be
supporting Ubuntu 14.04 and Ubuntu 16.04 ships with FreeType 2.6.1,
which is new enough that using the symbol is no-longer an issue.
The renaming of FT_Get_X11_Font_Format() happened in FreeType 2.6

remove xkb-default.patch
This was removed upstream in d5abf545971da717014d316127045fc19edbcd65
