tests: disable Linux linker version script for rustc <1.90.0

rustc <1.90.0 does not handle the version_script used in the Linux
test code -- skip using a version script with rustc <1.90.0 since this
is not testing essential functionality.

this cset can be reverted once the msrv for cxx moves past 1.89.0
