stress-buffer/libmedia_dev/rds-ctl: fix gcc-8.1 warnings
Fix various snprintf warnings of this type:
get_media_devices.c: In function ‘get_class’:
get_media_devices.c:147:33: warning: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size between 0 and 4095 [-Wformat-truncation=]
snprintf(fname, PATH_MAX, "%s/%s", dname, entry->d_name);
^~
get_media_devices.c:147:3: note: ‘snprintf’ output between 2 and 4352 bytes into a destination of size 4096
snprintf(fname, PATH_MAX, "%s/%s", dname, entry->d_name);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
