stream/tvi_v4l[2]: fix calculation of free RAM for buffers
Do a proper calculation of free RAM to be used as V4L buffers.
The code uses sysinfo to query the available RAM, however it used
ancient form available in some early development 2.3.x kernels.
Newer form reports the size in memory units (usually same as page size),
as result the code would fall back on 2 buffers even on multi GB system.
The commit does: Improve the check in configure to ensure that we
do use sysinfo struct with present mem_unit. Use free RAM instead of
total RAM (to avoid swapping). Tweak memory constants and simplify code.
