ob_get_binary_packages(), *ob_*_binary_parameter(): Improve "clean" naming

And fix unbound variables in ob_get_binary_parameter() and
_ob_set_binary_parameter().

Fixes:

	FAIL: tests/lib/ob_get_binary_parameter

 libopkbuild:
 
+  * Binary package parameters are stored internally now with fewer
+    conflicts.  Specifically, binary package names such as
+    "libncurses.6" and "libncurses++.6" no longer conflict, because the
+    non-alphanumeric parts of the names are different lengths.
+  * An unbound variable that could cause ob_get_binary_parameter() to
+    fail has been fixed.  The utilities called ob_get_binary_parameter()
+    after setting a variable of the same name, so the bug went
+    unnoticed.
   * ob_get_binary_parameter() is now covered by the test suite.
