Makefile: fix reconfigure check passing with prefix substring 

Example: Before when you passed "make tests TESTFILTER=Attitude"
and subsequently "make tests TESTFILTER=Atti" it found the string
"TESTFILTER=Atti" in "TESTFILTER=Attitude" and hence the check if
the configuration is already correct passed. The fix checks for
the configuration parameter including the subsequent space separator
and after that strips the space away again such that the list
VERIFIED_CMAKE_OPTIONS doesn't contain trailing spaces.
