[PATCH v3 7/9] tests/style: check qemu/osdep.h is included in all .c files

["Daniel P. Berrangé" <berrange@redhat.com>]

The qemu/osdep.h file must be included as the very first header in
all C source files, to ensure its definitions take effect over all
other header files, including system headers.
