passt, pasta: Add seccomp support

List of allowed syscalls comes from comments in the form:
	#syscalls <list>

for syscalls needed both in passt and pasta mode, and:
	#syscalls:pasta <list>
	#syscalls:passt <list>

for syscalls specifically needed in pasta or passt mode only.

seccomp.sh builds a list of BPF statements from those comments,
prefixed by a binary search tree to keep lookup fast.

While at it, clean up a bit the Makefile using wildcards.
