Michael Eischer 50053a85d3 rest: Adjust http2 missing eof test to golang >= 1.17.3, >= 1.16.10
The missing eof with http2 when a response included a content-length
header but no data, has been fixed in golang 1.17.3/1.16.10. Therefore
just drop the canary test and schedule it for removal once go 1.18 is
required as minimum version by restic.
