testsuite: riscv: valgrind: tolerate unhandled syscall

When running a riscv(32|64)-elf-targeting compiler on a
x86_64-linux-gnu with valgrind-3.18.1, it prints a multi-line warning
about an unhandled syscall, but the test works if we ignore those
lines to avoid an excess errors failure.

I've thus arranged for relevant pieces of the valgrind warning to be
pruned.

	* gcc.target/riscv/pr122215.c: Prune valgrind unhandled
	syscall multi-line warning.
