Remove is_buck2() calls from folly/debugging/symbolizer/test/validate…

…_folly_symbolizer.bzl

Summary:
buck1 is declared dead, is_buck2() checks will always return true. We can statically eliminate
these calls and associated conditional checks. folly/debugging/symbolizer/test/validate_folly_symbolizer.bzl was codemodded with libcst.
