The ::write() function used to signal a framebuffer fence in the unit
test is marked with the 'warn_unused_result'.
When building in debugoptimized mode not checking for the return
value causes issues at build time:
/test/fence.cpp:254:2: error: ignoring return value of function declared with 'warn_unused_result' attribute
Fix that by checking the ::write() return value and emitting an
error message in case the write fails.

Add a test for the Fence class by testing a Fence failure case, and
by testing a successfully signalled fence capture cycle.
