init: fix DumpState() logging

Fix two formatting issues in Action::DumpState(),

Old:
on ro.crypto.state=encrypted ro.crypto.type=file zygote-start
New:
on ro.crypto.state=encrypted && ro.crypto.type=file && zygote-start

Old:
on boot
  %sifup lo
  %shostname localhost
  %sdomainname localdomain
  %swrite /proc/sys/vm/overcommit_memory 1
New:
on boot
  ifup lo
  hostname localhost
  domainname localdomain
  write /proc/sys/vm/overcommit_memory 1

Also, now that we're importing many small rc files, it no longer makes
sense to call Parser::DumpState() after each import.  Therefore, move
the conditional to call Parser::DumpState() to after /init.rc and its
imports are parsed and after the late imports are parsed.

Test: Boot bullhead with DumpState() enabled and check the output
