It should not prevent to start mc cause lack of a subshell. Want to start with subshell disabled instead.

I"m not certain if this is related to the closed Ticket #3580 "Slow start because the subshell starts slow", but to avoid a very long startup time on certain Linux boxes, passing --nosubshell explicitly is required. Startup-time changes from almost 60 seconds without --nosubshell to 1 second if the subshell is disabled. This has become an issue in 2023, well after Ticket #3580 was closed.

@drankinatty this PR has nothing to do with the issue of slow startup. Here the startup would fail with an error message for an unsupported subshell.

There can be many reasons for slow startup. In order to find out what's happening you need to investigate.

Since the fix works, can the PR be pushed?
