build: fix cleaning configured stamp file

We have packages with their own parts appended to standard STAMP_CONFIGURED
(mostly with an underscore character).  This will render the current
STAMP_CONFIGURED_WILD setting invalid and the build system may miss a rebuild
on config change

 1. Build with config A
 2. Build with config B, yet .configured_A_xx did not get cleaned
 3. Return to config A, but rebuild will not happen because stamp file
    of config A still exists
