games-action/minetest: Executable needs PaX flag "m"

[Columbus240]

On a PaX enabled kernel, depending on whether CONFIG_PAX_MPROTECT is set, minetest crashes on loading a world or opening the mods menu because LuaJIT is blocked by the kernel.
This is fixed by setting the appropriate flag, using setfattr -v m -n user.pax.flags /usr/bin/minetest.
It would be nice if the ebuild would do this by itself.

I have already filed a bug in the minetest repo (minetest/minetest#5761) and got sent here, to the package maintainer.

I tried to use setfattr in pkg_preinst() and in pkg_postinst() and both times it didn't work. There are other binaries with PaX flags set. The ebuilds of these binaries should help.

If you have a look at app-emulation/wine-9999 from the Gentoo repo, you might notice that it has a line of inherit pax-utils and does pax-mark psmr "${D}"usr/bin/wine in multilib_src_install_all().
So I think this ebuild should also do the inherit part and do something like pax-mark m "${D}"usr/bin/minetest (if ! use dedicated) (and the same for minetestserver if use server || use dedicated), in src_install().

(To check that the flags are set correctly after installation use getfattr -n user.pax.flags /usr/bin/minetest{,server}
