fbdev: Use _SYSMEM_ infix for system-memory helpers

Change the infix for fbdev's system-memory helpers from _SYS_ to
_SYSMEM_. The helpers perform operations within system memory, but
not on the state of the operating system itself. Naming should make
this clear. Adapt all users. No functional changes.
