Introduce format string for pid_t
BeOS and Haiku on i386 use long for 32-bit types, including pid_t.
Using %d with pid_t therefore results in a warning.
Unfortunately POSIX:2008 does not define a PRId* string for pid_t.
In some places pid_t was previously casted to long and %ld hardcoded.
The predecessor of this patch added another upcast for the simpletrace
filename but was not applied to date.
Since new uses of pid_t with %d keep creeping in, let's instead define
an OS-dependent format string and use that consistently.
