Jeff Genovy b2170e4773 ICU-20718 Fix failing MSYS2 build due to current path confusion.
The Azure DevOps VM images that are used in the CI builds recently
updated the version of MSYS that is installed, which is causing the
MSYS builds to fail. It seems that this new version has issues with
using the shell cmd method in the makefiles to obtain the current path.

However, we can avoid this entirely by using the cygpath utility, which
also avoids the overhead of launching a new cmd instance just to get
the path. Unfortunately, it seems that older versions of MSYS don't
have this utility program included by default, though versions of 
MSYS 2 and up do have it included by default.

We can continue using the old approach for the older versions and use
the cygpath approach for new versions.
