s390/kexec_file: Fix potential segment overlap in ELF loader

[ Upstream commit 6339a3889ad4d0dd930ed7a1e873fb81d3e690f7 ]

When loading an ELF image via kexec_file the segment alignment is ignored
in the calculation for the load address of the next segment. When there are
multiple segments this can lead to segment overlap and thus load failure.
