remove dependency for lrelease-qt4

[dvzrv]

lrelease-qt4 should not be used during installation. qt4 is mega-dead and therefore lrelease-qt5 should be used instead, as the rest of the codebase uses python-qt5 already(?!).

This is one of the remaining points preventing me to move raysession to Arch Linux [community].

[dvzrv]

After testing, that this works (it does!), the default needs be changed to lrelease-qt5 to have no dangling dependency on qt4.

Oh yes I know this. lrelease-qt4 choose is a quickly done workaround to Can build with launchpad on ubuntu16.04 . There is certainly a better way to do.

have you got a "lrelease" executable on arch Linux ? On Ubuntu, I don't have lrelease-qt5 executable available but a "lrelease" that comes with qtchooser package.

It comes with qt5-tools.
