Improved support for GNU/kFreeBSD

- add kFreeBSD to NBI and CPUID
- add kFreeBSD to jcpuid/jbigi build scripts
- refresh debian patches to compensate for kFreeBSD changes
- i2prouter: Detect kFreeBSD and normalize its name
- clean up osid (switching to "elif") and adding support for detecting kFreeBSD
- update postinstall.sh; I2P cannot be installed using gij so postinstall.sh
  will not be run. If/when openjdk finally comes to kFreeBSD, we'll be ready for it.
