base.bbclass: define PACKAGECONFIG_CONFARGS before only sometimes appending to it

* just to make sure it's expaned by bitbake before it gets
  executed in shell
* e.g. with cmake.bbclass and cmake recipe (any recipe without
  PACKAGECONFIG options have this issue) it looks like this:
  bitbake -e cmake | grep EXTRA_OECMAKE=
  EXTRA_OECMAKE="     -DCMAKE_DOC_DIR=share/doc/cmake-3.14
    -DCMAKE_USE_SYSTEM_LIBRARIES=1 -DCMAKE_USE_SYSTEM_LIBRARY_JSONCPP=0
    -DCMAKE_USE_SYSTEM_LIBRARY_LIBUV=0
    -DCMAKE_USE_SYSTEM_LIBRARY_LIBRHASH=0     -DKWSYS_CHAR_IS_SIGNED=1
    -DBUILD_CursesDialog=0     -DKWSYS_LFS_WORKS=1
    \${PACKAGECONFIG_CONFARGS}"
