Fix multiple compilation issues on Linux

* Circular gal<->common dependency bites again. Add 'common'
  again to the 'kicad' target's link libraries. libgal.a depends
  on SHAPE_POLY_SET in common, but common depends on gal. This is
  not a real fix, but it unsticks Linux compilations. Fixing the
  circular dep is an existing bug: https://bugs.launchpad.net/kicad/+bug/1832229

* Missing LEGACY_HK_NAME for ACT_EndTuning: this was probably accidentally
  allowed on some other platform due to different wxString constructors.
  On Linux/GCC, it breaks.

* Unused include from /kicad in export_vrml.cpp. This is not findable
  on Linux, as pcbnew does not include the right dirs for this to be
  found. But it's not used, so just remove it.
