GNUmakefile: enable recovered wasm package tests

Move the standard library packages that were blocked by missing panic
recovery into the portable test set. Keep image excluded from bare wasm
because its tests require filesystem fixtures.

Also enable crypto/ecdsa in the fast WASI suite now that Goexit runs
deferred calls.
