Merge bitcoin/bitcoin#23811: scripts: match on EXE_FORMATS rather than name string

d1711a4 scripts: match on exe type over str in symbol-check.py (fanquake)
feee308 scripts: match on exe type over str in security-check.py (fanquake)

Pull request description:

  This is a minor change, but matching on the `EXE_FORMAT` is slightly simpler and more robust, and this reduces the diff for a future change I plan on making.
