Subject: [PATCH] TT#54410 Get rid of hardcoded checksum of sipwise.gpg file

We want to get rid of old sipwise gpg file as it contains weak key. To
do it we need either update this hardcoded value (and do it every time
when key is updated) or use the same behavior as it's used in
installer.

(cherry picked from commit 35bfe45d247c69c014b63fd96a7003519f765a08)
