man: remove the section suffix from page names in listDir()
After recent major changes to man's listDir() (starting at
223de3ec and ending with
1d752c04) man page names acquired
section suffixes in parentheses. For example, "aio.h" became
"aio.h (0p)". This page name format change broke URLs formed by joining
a section URL and a page name, e.g. "man:/(7)" + '/' + "bootup (7)".
The xdg-open "man:/(7)/bootup (7)" command opens this broken link in
KHelpCenter, which displays the "Manual Page Viewer Error" page.
The added section suffixes also break displaying man pages in KDevelop's
Man Pages documentation plugin.
Revert this breaking change by removing the section suffix rather than reformatting it into parentheses.
