  [Bolt] Explicitly request PIE in tests (#108818)

When clang is built with `-DCLANG_DEFAULT_PIE_ON_LINUX=OFF`, a number of
bolt tests fail:

    BOLT :: AArch64/build_id.c
    BOLT :: AArch64/plt-call.test
BOLT :: X86/dwarf5-dwarf4-types-backward-forward-cross-reference.test
    BOLT :: X86/dwarf5-locexpr-referrence.test
    BOLT :: X86/internal-call-instrument.s
    BOLT :: X86/linux-static-keys.s
    BOLT :: X86/plt-call.test

Avoid this by explicitly adding `-fPIE` and `-pie` to the default flags
in tests, so we don't depend on the clang-side default.
