[JSC] Speed up getStatusMap and increase robustness

https://bugs.webkit.org/show_bug.cgi?id=236559

Reviewed by Adrian Perez de Castro.

Collect test results in parallel. Also, ignore ssh errors during
collection (e.g. because the remote host is down) -- the main retry
loop will take care of that for us.

This should both avoid needless failures like
https://build.webkit.org/#/builders/31/builds/2432 and reduce the
latency when there are multiple remotes (e.g. for MIPS).
