arch/riscv/ricv_exception.c: Dump the process name at exception in user space

Browse source 
This helps in debugging loaded elf files in CONFIG_BUILD_KERNEL. If a user space exception occurs,
one would beed the process name in order to debug the correct process/elf file.

Only dumping the pid and name of the crashed task/thread doesn't help, since different processes
may have helper threads with the same name.
