wmfsm: Apply further Debian patches.

The individual patches no longer seem to exist, so I submit them together.
According to debian/changelog entries by Arthur Korn <arthur@debian.org>,
these patches include:
* fixed memleak introduced in 0.34-2 with the patch by Timo Benk.
  global char *mp[] was assigned the result of stdup() repeatedly
  without free. My ugly fix is to free it all up at the beginning of
  readFileSystems(). Now I'm a proud Perl coder ... closes: #196057
* memleak news: avoid it if there are more than 9 filesystems too.
* Fixed filesystem name corruption, thanks to Ralf Horstmann and Cristian
  Ionescu-Idbohrn for the patch.
