ci adjustments

* ubuntu:
  * only run coverage and additional warnings when main ci build works - use its generated tarball
  * trigger MSYS1 build, passing the run-id (needs to be adjusted to a "pull" later
* msys1+ubuntu:
  * use "build" instead of "_build"
  * upload config.log after the build - because we may need it to debug build issues
  * always upload the testsuite.log (additional build documentation)
* msys1:
  * drop GC install log and therefore extra prefix
  * building BDB with all relevant patches from MSYS2
  * GMP url changes, building it again for performance reasons
  * using msys-build instead of building Bison (only necessary for GC4)
  * enable NIST85, skipping extra IF106A as this hangs, ignoring failing NIST for now
  * ci cache adjustment:
    * remove split per matrix
    * split per software, enabling smaller updates
  * use CI tarball like for the minimal build
