[PATCH v2 1/3] tests/tcg: Make the QEMU headers available to the tests

[Ilya Leoshkevich <iii@linux.ibm.com>]

The QEMU headers contain macros and functions that are useful in the
test context. Add them to tests' include path. Also provide a header
similar to "qemu/osdep.h" for use in the freestanding environment.

Tests that include <sys/auxv.h> get QEMU's copy of <elf.h>, which does
not work without <stdint.h>. Make use of the new header in these tests
in order to fix this.
