 We run cargo update during USES=cargo ports builds to update specific
 crates and patch Cargo.lock for us.  For normal crates this is based
 on what's available in the vendor dir.  For Git sources this pulls
 new changes from the net instead even if we replace the source with
 a static path in a patch section in the config file.  Add a hack
 to skip this.
 
 This is for experimentation to solve [1].  For this to maybe be
 useful for USES=cargo, the patch-in-config feature also needs to
 be stabilized first.  It will be available in Rust 1.56.
