[PRQ#47592] Deletion Request for python2-flowui

MarsSeed [1] filed a deletion request for python2-flowui [2]: Unneeded package from 2015 for a Python2 module not developed since 2014. [a] Its AUR consumer, python2-voidwalker{,-git} is also discontinued since 2014 and broken due to its dependency, gdb no longer supporting Python2 modules. Safe to delete this package.
