[slave-buster] Armhf sairedis build fix (#6239)

Doxygen https://github.com/opencomputeproject/SAI/blob/master/Makefile#L23
 SAI submodule in libsairedis builds meta using doxygen
 Debian buster doxygen for ARMHF (32bit) fails to recursively
 read subdirectories to parse the header files.
 This issue is described at https://bugs.launchpad.net/qemu/+bug/1805913
 The solution to this is to add FILE_OFFSET_BITS to 64 as desribed at
 https://bugzilla.kernel.org/show_bug.cgi?id=205957

 This issue is not seen in stretch which has glibc 2.24 and is seen only
 on buster which has glibc version 2.28. The above bugs needs to be
 tracked to get rid of this PR change, once debian moves forward to next
 version.

 This PR addresses the readdir() issue for 32bit arch, by adding
 cflag _FILE_OFFSET_BITS=64 through cmake definition to the doxygen
 source downloaded from the debian buster.
