kobs-ng: test kernel version for redefines 

kobs-ng failed to build with 2.6.36, because enum tested with #ifndef

mtd.c: In function 'mtd_open':
mtd.c:696:42: error: 'MTD_FILE_MODE_NORMAL' undeclared (first use in this
function)
mtd.c:696:42: note: each undeclared identifier is reported only once for each
function it appears in
mtd.c: In function 'mtd_set_ecc_mode':
mtd.c:896:43: error: 'MTD_FILE_MODE_NORMAL' undeclared (first use in this
function)
mtd.c:914:43: error: 'MTD_FILE_MODE_RAW' undeclared (first use in this
function)

Do kernel version test before enum redefines.
