tdx-xwayland: drop stale ARM tune override

arm-defaults.inc was added to avoid CPU-specific package feeds by
collapsing ARM tunes in the distro. It used to set DEFAULTTUNE through
a distro override, and distro overrides win over the machine overrides
used by meta-freescale's imx-base.inc.

Since bd5e07c4c108 ("tdx-base/arm-defaults.inc: remove tdx-distro
override"), the include only makes an unqualified DEFAULTTUNE
assignment. The active SoC DEFAULTTUNE overrides now take precedence,
so this migrated include no longer changes the reference distro output.

It has essentially been non-functional for a year already, drop it
completely.
