Fix resolving relative paths for corral run
Corral was failing when running commands with a relative path to the binary. E.g. ../../build/debug/ponyc.
This change switches relative binary resolution from using FilePath.from to Path.join, in order to not fail if a path points to a parent directory, which is an error condition for FilePath.from.
corral run now also resolves relative paths against the current working directory first, before checking the $PATH environment variable.
Improved Error messages for corral run
corral run will now print more detailed error messages when it is not able to run the given command.
