Make the default umask a string

[syedriko]

Signed-off-by: Sergey Yedrikov syedriko@redhat.com

This is a correction to a previous commit that added the --umask command line parameter.
The default umask needs to be a string, otherwise the following happens:

2022-03-16 05:14:45 +0000 [error]: unexpected error error_class=ArgumentError error="wrong number of arguments (given 1, expected 0)"
2022-03-16 05:14:45 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.14.5/lib/fluent/supervisor.rb:714:in `to_i'

Which issue(s) this PR fixes:
None

Ah, sorry I missed it.
In addition, default values should be placed in Supervisor.default_options

fluentd/lib/fluent/command/fluentd.rb

Line 29 in 2036c4a

opts = Fluent::Supervisor.default_options

fluentd/lib/fluent/supervisor.rb

Lines 558 to 583 in 2036c4a
