UE: Don't look up binaries in PATH when the user specified a full path

When the user specifies a path such as ./test we'd incorrectly look for
the binary in the PATH environment variable and end up executing an
incorrect binary (e.g. /bin/test). We should only look up binaries in
PATH if the user-specified path does not contain a slash.
