quota: inherit pkgconfig

* missing dependency on pkgconfig-native was causing
  that PKG_CHECK_MODULES(DBUS, dbus-1) stayed unexpanded in
  configure script:
  checking for ext2fs_initialize in -lext2fs... yes
  quota/4.01-r1/quota-tools/configure: line 3746: syntax error near unexpected token `DBUS,'
  quota/4.01-r1/quota-tools/configure: line 3746: `        PKG_CHECK_MODULES(DBUS, dbus-1)'
  Configure failed. The contents of all config.log files follows to aid debugging
