Unrolled build for rust-lang#134972

Rollup merge of rust-lang#134972 - Skgland:master, r=Noratrieb

add .mailmap entry for myself

Seeing rust-lang#132474 in the bors queue I decided to check myself and noticed I was listed four times.
This fixed that by cannonicalizing all entries to use my username and the github no-reply email address, rather than some combination of name or username and different email addresses.
