Fix #8003
Signed-off-by: NViren Negi <meetme2meat@gmail.com>

As we're looking to expand what's in the WAL,
having old Prometheus servers ignore the new record types
rather than treating them as corruption allows for better
upgrade/downgrade paths.

Adjust some tests accordingly, so they're still testing what they're
meant to test.

This PR test that de-duplicated targets are actually started.

It is a unit test for this line of code:
https://github.com/prometheus/prometheus/blob/072b9649a30e06c71ddd1c64d25f71c4936e56ba/scrape/scrape.go#L457
which is working and necessary but was not tested yet.

It also tests that scrapes are started in the normal way, in the targets
limit test.

Direct syscalls using syscall.Syscall(SYS_*, ...) should no longer be
