syslinux: Avoid double `/boot` if bootprefix is enabled

This backend always explicitly emitted a `/boot` - but if
the global `sysroot.bootprefix` is enabled, then we can rely
on the outer code doing it.

Luckily this was caught by the unit tests here failing when
enabling `sysroot.bootprefix` by default.
