What steps will reproduce the problem?
(1) Start chromium with --v=1

What is the expected result?
Chromium should print the following log lines:
[5867:5867:0714/211544.354457:VERBOSE1:key_storage_util_linux.cc(53)] Password storage detected desktop environment: XFCE
[5867:5867:0714/211544.354490:VERBOSE1:password_store_factory.cc(226)] Trying libsecret for password storage.
[5867:5867:0714/211544.362965:VERBOSE1:password_store_factory.cc(229)] Using libsecret keyring for password storage.


What happens instead?
Chromium does not detect XFCE and prints instead:
[8849:8849:0714/213137.931289:VERBOSE1:key_storage_util_linux.cc(53)] Password storage detected desktop environment: (unknown)
[8849:8849:0714/213137.931333:WARNING:password_store_factory.cc(253)] Using basic (unencrypted) store for password storage. See https://chromium.googlesource.com/chromium/src/+/master/docs/linux_password_storage.md for more information about password storage options.

Please provide any additional information below. Attach a screenshot
and backtrace if possible.

I have created a fix for the problem and will upload it for code review.
