migrate: Fix several errors with passt-repair

The passt-repair helper is now merged, but alas it contains several small
bugs:
 * close() is not in the seccomp profile, meaning it will immediately
   SIGSYS when you make a request of it
 * The generated header, seccomp_repair.h isn't listed in .gitignore or
   removed by "make clean"
