benchmarks/vkoverhead: Revert "exorcise -Werror and unbreak on armv7"

This reverts commit f95a776840b0d53d446a8f219ed6ed5a7b135029.

As discussed with jbeich, this fix may fix the build, but it doesn't
lead to a working port.  Revert until a proper fix can be designed.

benchmarks/vkoverhead: exorcise -Werror and unbreak on armv7

This fixes the build on armv7, avoiding a bogus int conversion
warning.  While we are at it, turn static REINPLACE_CMD usage
into patch file as per policy.

benchmarks/vkoverhead: drop unused dependency

benchmarks/vkoverhead: add new port

vkoverhead is a tool for evaluating CPU-based overhead of Vulkan
drivers. It was inspired heavily by drawoverhead from piglit.

 ## Features
* extreme granularity for profiling specific scenarios
* simple to use
* CSV output for ease of script parsing
* zero dependencies
