bootz: rename NetBoot module to BootNet

Rename the NetBoot module to BootNet to avoid confusion with Apple's
NetBoot and better reflect the module's role within BootZ.

Updates include:
- Renamed module directory: NetBoot/ → BootNet/
- Renamed files and headers: NetBoot.cc → BootNet.cc, etc.
- Updated build output: netboot.sys → bootnet.sys
- Replaced all references in build scripts, source includes, and user-visible strings
- Fixed typo in SysChk.cc copyright

This unifies naming across modules and reinforces BootZ's modular identity.
