[Minios-devel] [UNIKRAFT PATCH] support: don't throw error message when not in a git repo

[Florian Schmidt <florian.schmidt@xxxxxxxxx>]

The gitsha1 script is used to create a version string for unikraft that
includes the git hash. However, if we are not building from a git repo
checkout, it will throw error messages on the command line. Suppress
these because there's little gain in them.
