libvduse: Provide _GNU_SOURCE when compiling outside of QEMU
When the libvduse sources are used by another project, it can not be
guaranteed that _GNU_SOURCE is set by the build system. If it is for
example not set, errors like this show up.
CC libvduse.o
libvduse.c: In function ‘vduse_log_get’:
libvduse.c:172:9: error: implicit declaration of function ‘ftruncate’; did you mean ‘strncat’? [-Werror=implicit-function-declaration]
172 | if (ftruncate(fd, size) == -1) {
| ^~~~~~~~~
| strncat
The simplest way to allow external complication of libvduse.[ch] by
setting _GNU_SOURCE if it is not already set by the build system.
