Fix runghc when $1_$2_SHELL_WRAPPER = NO
When that variable isn't on (which is always the case on Windows),
`runghc` naively attempts to invoke `ghc` by finding an executable
simply named `ghc`. This won't work if `ghc` doesn't exist (e.g., if
we're building GHC and using `ghc-stage2` instead). A simple fix is to
test for the existence of `ghc` beforehand, and if that fails, fall back
on `ghc-stage2`.
Fixes #11185.
