Add workaround for TruffleRuby and do not use File::SHARE_DELETE

[andrykonchin]

Fix logger on TruffleRuby.

TruffleRuby is missing a File::SHARE_DELETE constant that is in logger since #102. It was fixed in the TruffleRuby trunk and will be released in the next version.

This proposed temporary workaround in logger is needed to make it work on the current TruffleRuby release.

TruffleRuby issue truffleruby/truffleruby#3745

Also are maintainers open to add TruffleRuby on logger's CI?

There is only one failing test now:

Failure: test_shifting_size_not_rotate_too_much(TestLogDevice):
