tests/tcg: Don't #include <inttypes.h> in aarch64/system/vtimer.c

make check-tcg fails on Fedora with:

    vtimer.c:9:10: fatal error: inttypes.h: No such file or directory

Fedora has a minimal aarch64 cross-compiler, which satisfies the
configure checks, so it's chosen instead of the dockerized one.
There is no cross-version of inttypes.h, however.

Fix by using stdint.h instead. The test does not require anything
from inttypes.h anyway.
