A recent change in glibc 2.42.9000 [1] changes the return type of
strstr() and other string functions to be 'const char *' when the
input is a 'const char *'. This breaks the build in :

../tests/vhost-user-bridge.c: In function ‘vubr_parse_host_port’:
../tests/vhost-user-bridge.c:749:15: error: initialization discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
  749 |     char *p = strchr(buf, ':');
      |               ^~~~~~

Fix this by using the glib g_strsplit() routine instead of strdup().
