libvhost-user: Replace typeof with __typeof__

Browse Source 
Strictly speaking only -std=gnu99 support the usage of typeof and for
easier inclusion in external projects, it is better to use __typeof__.

  CC       libvhost-user.o
libvhost-user.c: In function ‘vu_log_queue_fill’:
libvhost-user.c:86:13: error: implicit declaration of function ‘typeof’ [-Werror=implicit-function-declaration]
   86 |             typeof(x) _min1 = (x);              \
      |             ^~~~~~

Changing these two users of typeof makes the compiler happy and no extra
flags or pragmas need to be provided.
