Migrate TestCommon to Chromium c++ style and remove un-used header.

Changes:
1) Run clang-format through source and header files.
2) Rename data member variables to use unix_hacker_ style.
3) Rename methods to use CamelCase style.
4) Rename file name to test_common.
5) Removed un-used test_common header.

BUG=331299
