Lua package version matching on Alpine

[sodface]

Hi, I'm doing some local testing on Alpine using their packaging tools and ran into an issue with meson because of the way Alpine's lua packages are named.

As a quick workaround I changed:

txproto/meson.build

Line 49 in 3f68be9

dependency('lua', version: ['>= ' + lua_ver, '< ' + lua_ver_maj.to_string() + '.' + (lua_ver_min + 1).to_string()]),

to dependency('lua5.4', which is certainly not the right way to handle this but got me on my way.

See discussion here too:
mesonbuild/meson#4553
