A release tarball carries generated files that a git tree does not, and
two of those bit us.
`MD5SUMS` is generated when a tarball is rolled. Each sub-source
extractor asserted `[[ -f MD5SUMS ]]` before copying it, so every one of
them failed outright the moment `monorepoSrc` was a git tree:
unpacking source archive /nix/store/...-source
source root is source
<exit 1>
Copy it only when it is there.
The generated sources are the other half: a checkout lacks
`gengtype-lex.cc` and friends, which a tarball ships pre-built, so they
have to be regenerated. Take flex and bison as native inputs when
`fromVCS` says the source is a checkout.
Tarball builds are unaffected either way.
