samples: mei: Fix building on musl libc

The header bits/wordsize.h is glibc specific and on building on musl
with allyesconfig results in

samples/mei/mei-amt-version.c:77:10: fatal error: bits/wordsize.h: No such file or directory
   77 | #include <bits/wordsize.h>
      |          ^~~~~~~~~~~~~~~~~

mei-amt-version.c build file without bits/wordsize.h on musl and glibc.

However on musl we get the follwing error without sys/time.h

samples/mei/mei-amt-version.c: In function 'mei_recv_msg':
samples/mei/mei-amt-version.c:159:24: error: storage size of 'tv' isn't known

  159 |         struct timeval tv;

Hence the the file has been included.
