cygprofile: switch scripts to use vpython

This should avoid import problems from various catapult dependencies
that are pulled via src/.vpython. One such problem was recently
mentioned in http://crrev.com/546790.

Also for consistency:
1. make all unittests executable
2. remove shebang and exec bit for the scripts that never produce output
   (utilities)
