Decommissioning java 1.5 (EOLed since October 2009) + removing outdated jdk16

vendors:
Remove any reference to bsdjava and freebsd Java Vendors, as the both are
outdated, have security issues and expired.

Mark icedtea6-stubs as broken as it doesn't build with any of the left supported
vendors.
Switch tuxguitar to be able to use openjdk16 [1]
