* util.c [LINUX] (clearbpt): Output panic message and return -1 if
breakpoint is already clear, like the non-LINUX version. All callers
check the TCB_BPTSET flag so this should never happen. Non-Linux
clearbpt and both versions of setbpt have equivalent checks. This was
the odd one out, so make it consistent.
