ifcodegen: Fix virtualenv creation on new macOS systemsv6.2.26.2.2

The virtualenv created on an newer macoOS systems doesn't work out
of the box when copying the executables because of a broken code signature.
The signature needs to be recreated ad-hoc, but as we need to use pip3
for the package installation this needs to be done right after the
virtualenv is created.

Fixes: AUTOSUITE-1645
