elfload: Fix alignment when unmapping excess reservation
When complying with the alignment requested in the ELF and unmapping
the excess reservation, having align_end not aligned to the guest page
causes the unmap to be rejected by the alignment check at
target_munmap and later brk adjustments hit an EEXIST.
Fix by aligning the start of region to be unmapped.
Fixes: c81d1fafa6 ("linux-user: Honor elf alignment when placing images")
