Fix modify_pc.py script to parse symbols in pc file properly

In the modify_pc.py script, regular expressions are used to parse
symbols and values. There are symbols separated from its value by a
colon(':') and by a equal sign('='). These two symbols are parsed by
regular expression but these regular expressions are incomplete since
content like below cannot be parsed properly.
  Cflags: -DAAAA=1 -DBBBB=...
In this case, it should be recognized as a colon symbol, which symbol is
"Cflags" and value is "-DAAAA=1 -DBBBB=...". But because of '=' in the
value, it was parsed as: symbol is "-DAAAA", value is "1 -DBBBB=...".

To resolve this bug issue, two anchors '^' and '$' are added to the
regular expression to represent the beginning and end of a string,
respectively.
