u-boot.inc: install u-boot-initial-env as ${PN}-initial-env in $D and $DEPLOYDIR
The common u-boot.inc can be used by multiple recipes in the same build for
different cores and/or multiple stages of the bootloader. Naming initial-env
with ${PN} prefix avoids clashes in deploy and rootfs between those recipes.
This fixes
69b3b093079c2ca2744d6c02747c5d1b5d3e7ecf that unconditionally
builds, installs and deploys u-boot-initial-env in the common u-boot.inc.
