Add myself to the committers-[ports|src].dot files It looks like I failed to do so when I got my ports bit...

[shurd]

Summary

Per conventions, I should be in committers-*.dot for

everwhere I have a commit bit.

Test Plan

Create png, try to find myself in it for a minute or two,

then give up and assume that since there were no errors, it's
fine.

[shurd]

Add db@ since she would have approved the committers-ports.dot commit I didn't make.
