gh-131372: Include LDVERSION and EXE in base_interpreter value (#142256)

* Include LDVERSION and EXE in base_interpreter value

In Fedora, build-details.json created and installed for python3.14t
contains "/usr/bin/python3.14" as the base_interpreter value.
Create a correct string, taking into account both LDVERSION and EXE
config variables, similarly to how it's defined in altbininstall in Makefile.

* Add news
