Fix various issues with the picobsd build script in -current:

+ declare some shell variables as 'local'
+ add a missing ';;' in a 'case' statement
+ centralize newfs options
+ properly override GID and UID when installing include files and libraries
+ add a missing '-r' in disklabel commands (maybe not necessary, but it
  does not harm and it was used in the RELENG_4 version)
+ no more require 'perl' when installing the secondary loader
+ use '-t rsa1' when invoking ssh-keygen
