test: use case-insensitive path checking on Windows in fs.cpSync tests

Browse Source 
In certain machine configurations on Windows, fs.readlinkSync() may
return a path with upper case drive letter while the other paths may be
constructed from a base path with a lower case drive letter (e.g.
from process.cwd()). Checking path mismatch in a case-sensitive
manner can lead to failure in some tests, specifically with the
Windows machine configurations in the Jenkins CI. Since paths
are case-insensitive on Windows anyway, compare them in a
case-insensitive manner in the tests.
