Fix array overrun when appending slash to paths

Fix it by extending the array sizes by one character. As the input is
limited to the maximum path length, there will always be place to append
the slash. As the php_check_specific_open_basedir() simply uses the
strings to compare against each other, no new failures related to too
long paths are introduced.
We'll let the DOM and XML case handle a potentially too long path in the
library code.
