Revert revision 1491887 so that modperl/local_env.t is skipped once again.

It evidently still isn't fixed :-( ... On Windows, with the test enabled it not only fails test 6, but also causes the following to fail (using either httpd-2.2.26 or httpd-2.4.7):

modperl/merge.t: 3, 6, 9
modperl/merge2.t: 3, 6, 9
modperl/merge3.t: 3, 6, 9
modules/cgi.t: 1-5
modules/cgi2.t: 1-5
modules/cgipost.t: 2-6
modules/cgipost2.t: 2-6
modules/cgiupload.t: 1-2
modules/cgiupload2.t: 1-2

It also causes the same failures (actually just 1-4 for cgi.t and cgi2.t) in trunk, tested with httpd-2.2.26. Moreover, the breakage isn't limited to Windows either: it also causes the following to fail on Fedora 20 (using either httpd-2.2.23 or httpd-2.4.9):

modules/cgi.t: 2, 5
modules/cgi2.t: 3
modules/cgipost.t: 4
modules/cgipost2.t: 4
modules/cgiupload.t: 1
modules/cgiupload2.t: 2

and again also in trunk (with httpd-2.2.23).
