rust/src/test/ui/command/command-setgroups.rs
Nikita Popov 0363655e8b Update test-various to Ubuntu 20.04
The test command-setgroups.rs is adjusted to skip on musl, where
`sysconf(_SC_NGROUPS_MAX)` always returns a dummy value of 32,
even though the actual value is 65536. I'm not sure why this becomes
relevant only now though, as this was apparently the case since
kernel 2.6.4.
