package/ogre: bump to version 1.12.9

Remove upstream patch [1].

tinyxml has been replaced by pugixml [2].

Switch to git download method since github release without
the complete source code in the tarball [3].

Update indentation of hash file (two spaces).

The sdl2-config.cmake generated by sdl2 package is broken for
cross-compilation since it add /usr/include/SDL2 in CFLAGS.

Such flags are unsafe for cross-compilation since it mixes
headers for the host and target.

sdl2-config.cmake must be removed from staging since
we are using autotools build system to build sdl2 package
[4][5].

ogre 1.12.7 only include <sys/sysctl.h> for iOS in order to
build with glibc >= 2.32 [6].
