[Buildroot] [PATCH] snappy: add dependency on host-pkgconf

Hello all. First Buildroot patch :-)

(This was discovered when adding leveldb which requires snappy. This missing
dependency is exposed when selection of this package is the only non-default
configuration choice ie you're not getting host-pkgconf via some other non-
default choice.)

Snappy doesn't configure without host pkg-config. The diagnostic from autoconf
is totally unhelpful, so for the benefit of others who might need this
prerequisite, when autoconf says this...

  configure.ac:42: error: possibly undefined macro: AC_DEFINE
        If this token and others are legitimate, please use m4_pattern_allow.
        See the Autoconf documentation.
  configure.ac:44: error: possibly undefined macro: AC_MSG_FAILURE

The solution is (probably) to add host-pkgconf to the packages's DEPENDENCIES
list.
