Subject: [PATCH] Prevent printing the EXEC_DIR when it's just a disk letter

This fixes following bug and also consistent with another 'cd /d "%EXEC_DIR%"' a few lines above.
When you're on the root of some disk running mvn.cmd prints an extra line with current dir before the correct output.
For example:

D:\>mvn -version
D:\
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
