defaultenv: boot/net: Boot initramfs from tftp if present
Use an 'initramfs' file if it exists instead of nfsroot. This offers the
possibility to quickly boot complete filesystems as initramfs without
the need to flash an SD-card or similar. If the initramfs does not
exist, it uses the default nfsroot mechanism.
