Subject: gnu: direnv: Change to the go-build-system.

The go-build-system is slightly more appropriate, and switching resolves an
issue with combining the 'unpack phase from the gnu-build-system, and the
'setup-go-environment from the go-build-system. With both of those phases
creating a directory, the first-subdirectory call at the end of the 'unpack
phase can return different values depending on the filesystem ordering.

* gnu/packages/shellutils.scm (direnv)[source]: Use the git repository, as
this works better with the go-build-system.
[build-system]: Change to the go-build-system.
[arguments]: Adjust for the go-build-system.
[native-inputs]: Remove go.
