Fix libafs_tree's cross-architecture support

Browse Source 
The results of libafs_tree are supposed to build on any platform that
shares the same basic kernel code, but this had broken in two ways:
libafs_tree was including a pre-built afs/param.h, which needs to be
regenerated on different architectures, and the Linux kernel build
makefile was being pre-generated despite having some architecture-specific
options.

Copy over more of src/config and postpone generation of afs/param.h and
generation of libafs/Makefile to the libafs build.

Remove the substitution of AFS_SYSNAME from make_libafs_tree.pl; it was
unused and now definitely shouldn't be used since it will break the
architecture-independence of the resulting tree.
