gh-109033: Return filename with os.utime errors

rpigott · rpigott · commit 9f064ec641bb · 2023-09-06T14:48:31.000-07:00
The filename was previously intentionally omitted from exception becuase
"it might confuse the user". Uncaught exceptions are not generally a
replacement for user-facing error messages, so obscuring this
information only has the effect of making the programmer's life more
difficult.
