[static] Mark some tests unsupported.

In the prior commit we opened static binaries for all ELF platforms when
requested. For some reason, the ImageInspectionELF module is split out
into its own library when building stdlib as a static library. However,
there are still references to lookupSymbol from swiftCore to
ImageInspectionELF, which cause lazy binding errors at runtime which
foul up these unit tests. Currently it is unknown whether it is
necessary to keep splitting out ImageInspectionELF like this; on its
face, this seems rather unnecessary.

Until then, mark these tests unsupported when stdlib exists as a static
library, since these tests use the dynamic version of stdlib, and won't
have the correct references to ImageInspectionELF.
