Fix macos bug deleting too many filesHEADmaster

Since #10209 we've been noticing that on macos after running `make
clean` the `coroutine/arm64/Context.S` file is missing, causing
subsequent make calls to fail because `Context.S` is needed to build
`Context.o`.

The reason this is happening is because macos is case-insensitive so the
`.s` looks for `coroutine/arm64/Context.s` and finds
`coroutine/arm64/Context.s`. This does not happen on linux because the
filesystem is case sensitive.

I attempted to use `find` because it is case sensitive regardless of
filesystem, but it was a lot slower than `rm` since we can't pass
multiple file names the same way to `find`.

Reverting this small part of #10209 fixes the issue for macos and it
wasn't clear that those changes were strictly necessary for the rest of
the PR.

We changed the original code to use `rm` instead of `delete` because it
is not standarized on POSIX.
