kselftest/arm64: mte: fix printf type warnings about longs

When checking MTE tags, we print some diagnostic messages when the tests
fail. Some variables uses there are "longs", however we only use "%x"
for the format specifier.

Update the format specifiers to "%lx", to match the variable types they
are supposed to print.
