armv8: check the core state to pass the correct arch to gdb

Commit 3799eded6761 ("target/aarch64: add support for
multi-architecture gdb") passes the constant string "aarch64" as
architecture to gdb. This is not working if the core is running
in 32 bits mode; gdb reports:
	Truncated register 8 in remote 'g' packet
then closes the connection with OpenOCD.

Make the architecture string dependant from the current state of
the core.
