rS292584: Set env vars from values on the efi loader command line.

Summary

Examine each cmdline arg and if it contains an '=' convert it to ascii and pass it to putenv(). This allows var=value settings to come in on the command line.

This will allow overriding dhcp server-provided data in loader(8), as discussed in PR 202098

Test Plan

I don't have any systems to test this change on.
