tests/docker: gcc-10 based images for ppc64{,le} tests
A newer compiler is needed to build tests for Power10 instructions. As
done for arm64 on
c729a99d2701, a new '-test-cross' image is created for
ppc64 and ppc64le. As done on
936fda4d771f, a test for compiler support
is added to verify that the toolchain in use has '-mpower10'. Finally,
Unused images (docker-power-cross and docker-ppc64-cross) are removed.
