luafilesystem: remove LARGE_FILE constraint

Add a patch to luafilesystem so that it builds correctly when large
files are not supported. This allows to remove the dependency of
luafilesystem on large file support on the toolchain. Packages such as
cgilua, wsapi and xavante, which depend on luafilesystem, also get
their dependency on large file support removed.

Fixes bug #2359.
