libraw1394: add patch to fix CLOCK_MONOTONIC_RAW build problem

Browse Source 
CLOCK_MONOTONIC_RAW is a fairly recent addition, which may not be
available in old C libraries/kernels. This commit adds a libraw1394
patch that makes the use of CLOCK_MONOTONIC_RAW optional. The patch
has been submitted upstream.

Subject: [PATCH] testlibraw: build the CLOCK_MONOTONIC_RAW test conditionally
CLOCK_MONOTONIC_RAW is a somewhat recent addition, and some older
toolchains/kernels may not have the support for it. Therefore, we
build the part of the test that uses CLOCK_MONOTONIC_RAW only when
this definition is available.
