Morten Linderud 37e893b1bd cmd/cgo: include seed string with -frandom-seed for lto 
cgo is built with -flto the symbols in runtime/cgo is going to include random numbers which would make builds unreproducible.

Settings -frandom-seeds ensures this is consistent across builds, and to ensure we always use a reproducible seed across builds we use the actionID as the seed string.

runtime/cgo built with "-frandom-seed=OFEc9OKoUMJwh3-5yFCH" would output the following:

    $ strings --all --bytes=8 $WORK/b055/_pkg_.a | grep "gnu.lto_.profile"
    .gnu.lto_.profile.8403a797
    .gnu.lto_.profile.8403a797
    .gnu.lto_.profile.8403a797
