net-p2p/c-lightning: fix build on GCC architectures

Needs C11 compiler:
cc1: error: unrecognized command line option "-std=gnu11"

Needs include sys/types.h in fdpass.c:
ccan/ccan/fdpass/fdpass.c: In function 'fdpass_send':
ccan/ccan/fdpass/fdpass.c:16:12: error: 'register_t' undeclared (first use in this function)

16 |   char buf[CMSG_SPACE(sizeof(fd))];
   |            ^~~~~~~~~~
