[Native] Building Prestissimo on AmazonLinux2

[majetideepak]

Amazon Linux 2 is the default distro on Amazon EC2 instances. It will be useful to provide a build script so that users of Amazon cloud can deploy Prestissimo.

Velox has a PR to support AL2 here facebookincubator/velox#3568
We need to include the additional Prestissimo dependencies in the build script.

With fizz, I see the following build error
‘TCP_ULP’ was not declared in this scope
Reported here
facebookincubator/fizz#85

I think for OSS community, we can only support CentOS Stream8.

@wanglinsong we want to have AmazonLinux2 as part of CI testing. We don't have to provide releases.

I posted a potential fix for facebookincubator/fizz#85 there.
The current AWS SDK C++ version "1.9.96" is Velox failed to build as well.
Version "1.9.379" worked.

Finally, I encountered random node crashes as reported here facebookincubator/velox#3800 when executing queries which is now fixed.
When executing queries, the SSD cache file writes failed since ODIRECT is not supported on most EC2 instances.
This can be avoided by passing the -ssd_odirect=false flag to Prestissimo.
