gitaly: Fix gitaly-git2go binary name (#136569)

e7f8fe4f67
changed the binary name to always end with its module version. This
makes sure gitaly's internal version references are set to the package
version and renames the binary, postfixing it with the package
version.

(cherry picked from commit d14e9188d1)
