PR 33801 strip doesn't remove .gnu.lto_.opts

OK, so people want to be able to partly destroy gcc slim LTO object
files.  I don't see why not, despite HJ's policy-setting slim lto
strip -R tests.  I also don't see why it matters that objcopy/strip
won't similarly break LLVM objects (pr33271).

So out goes the slim lto strip -R tests, and the strip-debug test
expecting slim lto files won't be modified in any way.  strip-debug
now removes a FILE symbol, which isn't unreasonable.
