BaseTools: Add the support for character '<' and '>' in the map file

Current the regex for the symbol in the map file doesn't support the '<'
and '>' character, while user use Lambda Expression (C++11 feature), it
would generate the something like @V<lambda_xxx>@ in the map file which
cause build fail to parse the symbol in map file.
