css: reset font size for blame oid

In Firefox, the hashes in the blame UI are out of step with the line
number and content leading to ever increasing vertical misalignment.

This is caused by the .oid class setting font-size to 90%, so override
this back to 100% for the blame case, bringing the height of lines in
all three columns of the table back into step.
