[lldb/test] Fix TestLoadUnload

[mib]

Summary

[lldb/test] Fix TestLoadUnload failure introduced in e0dbd025131c4d77d8a5050a91d391d950529a8c

It seems that env_cmd_string is declared and used few lines under this
self.runCmd expression. I guess this is some left-over from an older
version.

Looks good, thanks. This is a leftover from a previous version of that patch caused by me mailing patches between different operating systems.
