Remove the stale LLDB-Info.plist which was only used by TestHelp.py. The latter would try to parse the version number from the plist and use that to verify the version in the help output. Of course this never matched so it would fall back to matching any arbitrary version. This patch does *not* change the real LLDB-Info.plist.in file which is used for the LLDB Framework.
