Bug description:ext/standard/tests/file/copy_variation5.phpt fails when run on bind mount

Description:
------------
The following test fails when run inside a case insensitive bind mounted
filesystem (f.e. inside a container):

Test copy() function: usage variations - destination file names(case
sensitive) [ext/standard/tests/file/copy_variation5.phpt]

This both happens when running the test inside a filesystem mounting a
Windows NFS path into the container and when mounting a MacOS APFS path
into the container. This most likely happens with other filesystem too
since there is no guarantee that a linux mounted filesystem is case
sensitive.

Expected result:
----------------
test should be skipped if the filesystem it is run on is case
insensitive

Actual result:
