[S390] clean up linker script using new linker script macros.

Browse source 
Note that this patch moves .data.init_task inside _edata.  In
addition, the alignment of .init.ramfs changes: It is now PAGE_ALIGNED
and __initramfs_end is arbitrarily aligned; Previously it was
only aligned to a 0x100-byte boundary, and always ended on an even
byte.

This change results in fewer output sections and in some data being
reordered, but should have no functional effect.
