gh-35094: To determine GAP_SO sage.env looks for libgap.so but it should look for libgap.so*

### 📚 Description

In short, sometimes there is no `lib**.so` available, but only
`lib**.so.*`. This breaks GAP and Singular related things.
See #33446 for details.

Closes #33446

### ⌛ Dependencies
Depends on #35093 #34391 (GAP update to 4.12.2)

URL: #35094
Reported by: Dima Pasechnik
Reviewer(s): Matthias Köppe

Author: Release Manager
