6d382d30d9 ipl_tools: Allocate string buffer dynamically
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);
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

cmd_chreipl.c: In function ‘set_reipl_type_helper’:

9f8d245f92 ipl_tools: Copy strings correctly
Use util_strlcpy() to copy strings correctly and get rid of the
following GCC8 compile warnings:

main.c: In function ‘main’:
main.c:34:2: warning: ‘strncpy’ specified bound 256 equals destination
size [-Wstringop-truncation]
  strncpy(g.prog_name, argv[0], sizeof(g.prog_name));
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In function ‘set_bootprog’,
    inlined from ‘parse_chreipl_options’ at cmd_chreipl.c:510:4:
cmd_chreipl.c:185:2: warning: ‘strncpy’ specified bound 11 equals
destination size [-Wstringop-truncation]
  strncpy(l.bootprog, bootprog, sizeof(l.bootprog));
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

cmd_chreipl.c: In function ‘set_reipl_type’:
cmd_chreipl.c:297:2: warning: ‘strncpy’ specified bound 15 equals
destination size [-Wstringop-tr uncation]
  strncpy(l.dev, dev_name, sizeof(l.dev));
