Fix relative CMAKE_USER_MAKE_RULES_OVERRIDE (#11725)

In commit 295b5b60 (Honor CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile,
2010-06-29) we started passing the value of this variable when building
a try_compile project.  If the variable contains a relative path it must
be treated with respect to the file where it is first used.  Ensure that
the value is converted to a full path so that it is correctly referenced
in the try_compile projects.
