tests/sys/snprintf: use printf_long_long 
This is required to support printing 64 bit numbers, as is done in the
test.

In addition that 64 bit formatting test is feature gated, so that users
can simply comment out the `USEMODULE += printf_long_long` to fit tiny
boards.

snprintf

This test aims to test if the stdio implementations correctly implements standard format specifiers. Instead of relying on the transport of stdout to be fast and reliable, it will use snprintf to format in-memory and compare in the app with correctness.
