Make it build, and adhere to Arch standards more

• Its vendored qwt-lib thing needs a straightforward patch because of
  something that I hear Qt 5.15 broke.

• Git submodules are supposed to be specified as sources and sorted out
  in prepare. This was incidentally moderately necessary to sort out
  because the qwt patch needs the submodules to be up to date, so either
  the patch application had to be shifted to build, or the submodules to
  prepare.

• Improve the package version by pulling something from Git.
  In theory this package should probably also be renamed to
  entropy-piano-tuner-git, but upstream looks pretty dead. I dunno.
  Anyway, 1.2.0.r27.gee7857a > git. (And not just in meaningfulness; in
  version comparison, too, so an epoch bump isn’t needed.)
