remove dependency on /usr/bin/python

[pgajdos]

Fixes bsc#1212476.

Changes proposed in this pull request:

• shebangs include /usr/bin/python3.11 instead of /usr/bin/python3, thus

:/ # rpm -qR python3-kiwi | grep bin
/usr/bin/python3.11
:/ #

Why aren't you doing this as a buildroot policy?

[pgajdos]

Not sure I understand, sorry.

In this case, we call our package python3-kiwi and therefore it makes sense to link to /usr/bin/python3 shebang.

Meh, even if this should be a brp instead of a script, I don't care enough to quibble over it.
