[LTP] [PATCH] tst_kvercmp.sh: strip '+' when $(EXTRAVERSION) is blank

[Zhao Gongyi]

$(EXTRAVERSION) defines an even tinier sublevel for pre-patches
or additional patches. It is usually some non-numeric string
such as "-pre4", and is often blank. When $(EXTRAVERSION) is blank,
there may be a extra '+' which shoud be stripped.
