net/tap-solaris.c: Include qemu-common.h for TFR macro

In commit a8d2532 we cleaned up usage of the qemu-common.h header
so that it was always included from .c files and never from other .h files.
We missed adding it to net/tap-solaris.c (which previously was pulling it
in via tap-int.h), which broke building on Solaris hosts.
