Don't set the MSYS env var globally (#1329)
b2d865f18051b21447 introduced a call to exportVariable() to export the MSYS env
var, which configures the symlink strategy for MSYS2/cygwin binaries it calls.

By setting the env var globally, this also changes the behaviour of other MSYS2
using tools in a CI job, and also overrides MSYS configuration set by the user,
which I think was not intended.

To avoid this leakage set the MSYS env var only for the commands which
@actions/cache calls.

Fixes #1312
