Allow non-current user to own the directory which is built by ko

[SaschaSchwarze0]

Changes

Go is running some Git commands to determine version control information of the directory that it builds to attach them as metadata to the binary. This leads to BuildRun failures when the directory is not owned by the current user:

go version go1.19.6 linux/arm64
ko version 0.12.0

2023/02/25 11:42:11 Unexpected error running "go build": exit status 1
# cd /workspace/source; git status --porcelain
fatal: detected dubious ownership in repository at '/workspace/source'
To add an exception for this directory, call:

	git config --global --add [safe.directory](http://safe.directory/) /workspace/source
error obtaining VCS status: exit status 128
	Use -buildvcs=false to disable VCS stamping.

In Shipwright, it is more or less always the case that the user is not owning the directory. The reason is that /workspace/source is an emptyDir volume that root is owning.

The error already contains the solution that I am using = adding it as a safe directory.

Release Notes

The ko sample build strategy now makes the source directory a Git safe directory so that Go builds can retrieve version control information
