workflows: _really_ fix Boost caching?..

actions/cache@v2 doesn't work on windows-2016 images, since those
contain the GNU tar, which cannot work with \ as path separator.  This
was fixed in package @actions/cache v1.0.5, which is used by action
actions/cache@v2.1.4 [1][2].

In addition, it simply couldn't find tar.exe on those images thanks to
my action cleanup-path, which removed the corresponding directory (I
think it was Git's bin/) from PATH.  It worked for windows-2019 images
thanks to them containing tar.exe in System32.  Solved by turning
cleanup-path into a JavaScript action with a "post" step, which restores
the original PATH value.
