devops: fix firefox-beta build on Windows 10 (#12477)
Instead of using 64-bit version of MINGW that comes with Git Bash,
we now switch to the one provided by the mozilla-build on windows,
which is 32-bit.

This patch also reverts the previous attempt that was defining the library names
for redistribution. It should work without them as well.
