selftests: drv-net: fix missing include in ncdevmem

Commit ca9d74eb5f6a ("uapi: add INT_MAX and INT_MIN constants")
recently removed some includes of limits.h in uAPI headers.
ncdevmem.c was depending on them:

  ncdevmem.c: In function ‘ethtool_add_flow’:
  ncdevmem.c:369:60: error: ‘INT_MAX’ undeclared (first use in this function)
  369 |         if (endptr == id_start || flow_id < 0 || flow_id > INT_MAX)
      |                                                            ^~~~~~~
  ncdevmem.c:77:1: note: ‘INT_MAX’ is defined in header ‘<limits.h>’; did you forget to ‘#include <limits.h>’?
