Subject: [PATCH] reexport/{fsidd,reexport}.c: Re-add missing includes

Older uClibc-ng requires <unistd.h> for close(2), unlink(2) and write(2),
<sys/un.h> for struct sockaddr_un.

Fixes: 1a4edb2a ("reexport/fsidd.c: Remove unused headers")
Fixes: bdc79f02 ("support/reexport.c: Remove unused headers")
