Merge bitcoin#25288: test: Reliably don't start itself (lint-all.py runs all tests twice)

BACKPORT NOTE:
only left-over changes has not been done previously is replacing a mask "lint-*" to "lint-*.py" and it's done

f26a496 test: clean up all-lint.py (Martin Leitner-Ankerl)
64d72c4 test: rename lint-all.py to all-lint.py (Martin Leitner-Ankerl)

Pull request description:

  When running `./test/lint/lint-all.py`, the script runs all tests but
  also calls itself because the comparison with `__file__` doesn't work.

  Comparing resolved paths gives reliable comparison, and lint-all.py doesn't call itself any more
