rust: Remove passing test cases from the exclude list in the Rust OE self-test.

There were some rust tests which were FAILing only for mips architectures.
Hence, they were added to the exclusion list to avoid the failures when
running rust oe-selftest for mips architectures.The current yocto framework
disabled the rust oe-selftest for mips architectures.Hence, these tests have
been added back to the test framework.

The rust-1.79 has been successfully tested on X86, X86_64, ARM, AARCH64 and
PPC Architectures with the current test inclusions.
