Update to latest Go and u-root

[rjoleary]

This should fix the dependabot warnings.

This change also adds support for building the initramfs on Mac and makes the switch to using Go modules.

Tested with task -fv core:loader

I don't understand Go modules. The error is:

[image:rootfs] 	go get github.com/u-root/cmds/core/backoff
[image:rootfs] 	* package github.com/u-root/cmds/core/basename: -: no required module provides package github.com/u-root/cmds/core/basename; to add it:
[image:rootfs] 	go get github.com/u-root/cmds/core/basename

The github.com/u-root/u-root is inside the go.mod, so I expect this to work.

It looks like I need to change github.com/u-root to github.com/u-root/u-root. I'll fix this then, attend to this next error:

[image:rootfs] 	* package github.com/u-root/u-bmc/cmd/socat: -: no required module provides package github.com/u-root/u-bmc/cmd/socat; to add it:
