automation: Update ECLAIR analysis configuration

The Xen configurations for the ARM64 and X86_64 ECLAIR analyses
is currently held in fixed files under
'automation/eclair_analysis/xen_{arm,x86}_config'. The values
of the configuration options there are susceptible to going stale
due to configuration option changes.

To enhance maintainability, the configuration under analysis is
derived from the respective architecture's defconfig, with suitable
changes added via EXTRA_XEN_CONFIG.
