task_current_syscall
This adds the new function task_current_syscall() on machines where the
asm/syscall.h interface is supported (CONFIG_HAVE_ARCH_TRACEHOOK). It's
exported for modules to use in the future. This function safely samples
the state of a blocked thread to collect what system call it is blocked
in, and the six system call argument registers.
