Hao Wu 9fdf31789a MdePkg/BaseLib: Avoid reading content beyond string boundary 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=705

As mentioned in the above Bugzilla link by Steven, within the function
PathCleanUpDirectories(), when executing command:
"cd ."

under Shell, the input parameter 'Path' string will have string length
less than 2. Hence, it is possible for the below statement:
"if (StrCmp (Path + StrLen (Path) - 2, L"\\.") == 0) {"

to read contents before the string boundary.

This commit adds additional checks to avoid this.
