scripts: dts: Replace bare 'except's in old scripts

A bare 'except:' can do some annoying stuff like eat Ctrl-C (because it
catches KeyboardInterrupt). Better to use 'except Exception:' as a
catch-all.

Even better might be to catch some more specific exception, because even
'except Exception:' eats stuff like misspelled identifiers.

Fixes this pylint warning:

    W0702: No exception type(s) specified (bare-except)

Fixing pylint warnings for a CI check.
