[lldb][test] Re-enable import-std-module tests on Linux (#157649)

This reverts commit 76bd5da.

These were originally skipped for
llvm/llvm-project#137046 because they were
failing on Fuchsia buildbots.

I couldn't locally reproduce the Linux failures from back then (and
maybe they have been fixed by something else since then).

We want to re-enable these tests because they are one of the few API
tests in the `libcxx` category that we skip on Linux. So the libc++
pre-merge CI doesn't catch these test failures. To avoid churn caused by
this missing coverage, it would be great if we ran these on Linux again.
