[PATCH 13/15] qemu: Assume QEMU_CAPS_OBJECT_MEMORY_FILE_ALIGN

[Michal Privoznik]

Introduced in QEMU's commit of v2.12.0-rc0~148^2~4 the .align
attribute of memory-backend-file is always available for all QEMU
versions we support (4.2.0, currently). Therefore, we can assume
the capability is always set and thus doesn't need to be checked
for.
