Use util_asprintf() to allocate memory for the string buffers
dynamically and get rid of the following GCC8 compile warnings:
system.c: In function ‘print_fw_str’:
system.c:86:46: warning: ‘%s’ directive output may be truncated writing
up to 4095 bytes into a region of size 4082 [-Wformat-truncation=]
snprintf(path, sizeof(path), "/sys/firmware/%s", file);
^~
system.c:98:19:
read_fw_str(str, path, sizeof(str));
~~~~
system.c:86:2: note: ‘snprintf’ output between 15 and 4110 bytes into a
destination of size 4096
snprintf(path, sizeof(path), "/sys/firmware/%s", file);
