Always mark .probes section as writable.
Allocated section needs to be writable when creating pic shared objects
because we store relocatable addresses in them. We used to make this
read only for non-pic executables, but the new semaphore support relies
on having a writable .probes section to put the enabled variables in.
* includes/sys/sdt.h (ALLOCSEC): Define unconditionally as "aw".
