freebsd-to-rtems.py: Multiple fixes and supporting modifications

+ SED_PATTERN was broken when IPV6 enabled. The sed produced a
  zero length rtems-bsd-config.h.
+ "make install" without all did not produce GENERATED_FILES
+ Install .h files in contrib/altq. Needed by new libc commands
  being added shortly.
+ Do not copy <sys/uio.h> and <sys/_iovec.h> from FreeBSD. They
  are provided by RTEMS now.
+ net/if_stf.c appears to be strictly IPV6 functionality. Make building
  it conditional on IPV6.
