Add nethunter.root template (#1445)

This app requires DAC_OVERRIDE, DAC_READ_SEARCH, SYS_PTRACE, SYS_ADMIN
(for /data/local r/w) and SYS_CHROOT, SETGID (to run chroot and run it's
processes)

Devices with NetHunter installed is already considered compromised due
to lack of security features(like SELinux), therefore users are advised
not to store private data

It's not really worth restricting more capabilities of the app.
