sys-apps/likwid-4.3.4: migrate to lua-single.eclass

Supports lua5-2 and lua5-3 as per notes in the original ebuild, builds
fine against either.

Nb. on my system, even before the migration this ebuild only succeeds if
I force MAKEOPTS='-j1' - otherwise while linking likwid executables the
linker cannot find the package's own liblikwid.so.

Adding a separate package.mask line for migrated ebuilds because there
is still one ebuild in the tree which requires the package-wide mask.

Closes: https://bugs.gentoo.org/752858
