Rollup merge of rust-lang#58900 - Mark-Simulacrum:ignore-should-panic…

Ignore should_panic tests on android

These tests currently segfault sometimes. Android is a tier-2 target so
this is fine to disable instead of fixing.

Unfortunately, this isn't quite enough as rustdoc doesn't currently
correctly interpret the --exclude-should-panic flag (i.e., ignores it).
That proved to be harder to fix than I had time for so we're going to
leave it and hope that at least some of the failures are fixed.

Hopefully alleviates rust-lang#55861; I don't have the time to investigate fixing rustdoc.
