PR13386: avoid _stp_printf() crash for null context / %M or %m
If _stp_printf() were invoked with %M or %m directive that resulted in
an error, it likes to write into the current stap probe handler
context about it. However, _stp_printf is sometimes used outside
probe handler context, in which case no context is actually available,
such as during module_exit(). So we tolerate a null context pointer
(it just having been deallocated). Note that there don't exist any
current %M/%m outputs in the runtime that could trigger this
NULL-deref, so this is only a prophylactic measure.
* runtime/vsprintf.c (_stp_vsprint_memory): Tolerate null context.

PR13386: disable preemption around printing-happy parts of *module_exit().
* translate.cxx (c_unparser::emit_module_exit): Since we use stp_printf
(that internally is preempt-sensitive), we need to disable preemption
(or at least cpu switching) during this stage.
