Subject: [PATCH] Use PHP_OS rather than php_uname, which may be disabled

A user just logged on to the #mediawiki channel to ask for help because his
webhost disallowed php_uname(), causing wfIsWindows() to crash. Google
autocompletes 'php_uname()' to 'php_uname() has been disabled for security
reasons', so it is probably not uncommon. Consulting the PHP_OS constant
instead side-steps the problem nicely.
