Currently we disable kbind(2) for static program from libc.a's
preinit hook. Delete that and instead have the kernel disable kbind
at exec-time if the program doesn't have an ELF interpreter. For
now, permit userland calls to disable it when already disabled so
existing static programs continue to work.
prompted by deraadt@ questioning about the call in libc.a
