depfixer: Cache searching of install_name_tool
This gives a significant speedup in large projects such as gst-build
since now we only search for the tool once. Speed-up on Windows:
```
meson install:
before: 15.3 seconds
after: 5.4 seconds
meson install --only-changed:
before: 11.6 seconds
after: 2.7 seconds
```
