This patch standardizes the error messages when a syscall is not
available to be in the format: "ABC and DEF syscalls are not available."

Fixes#61355. The __dso_handle decl was introduced incorrectly into the startup
objects during the integration test cleanup which moved the integration tests
away from using an artificial sysroot to using -nostdlib. Having it in the
startup creates the duplicate symbol error when one does not use -nostdlib.
Since this is an integration test only problem, it is meaningful to keep it in
the integration test anyway.

The test binaries are built like any other executable but with two
additional linker options -static and -nostdlib.
