[Intel-gfx] [PATCH 1/3] intel-gpu-tools: fix problem with redefinition of mmap64

[tim.gore at intel.com]

From: tgore <tim.gore at intel.com>

In android builds there is no reliable way to determine if mmap64 is defined
or not, and this sometimes leads to a compile error due to its re-defnition.
So this commit avoids its use altogether in intel-gpu-tools for Android builds,
unless the HAVE_MMAP64 macro is defined.
