docs-xml:manpages: allow for longer version strings

The default value (30) truncates "Samba 4.21.0pre1-DEVELOPERBUILD" to
"Samba 4.21.0pre1-DEVELOPE" in the bottom left corner of the man page.
("Samba 4.21.0pre1-DEVELOPE" is only 25 bytes long, not 30, but let's
not worry about that).

On narrow terminals (< ~75 columns) this makes it more likely that
the version string will run into the date string.
