Amir Ayupov ab14eb23b6 [BOLT][test] Replace /dev/null with temp file (#73485)
NFC processing time script identifies tests by output filename.
When `/dev/null` is used as output filename, we're unable to tell the
source test, and the reports are unhelpful.
Replace `/dev/null/` with `%t.null` which resolves the issue.
