perf: Add libdw unwind support to perf-libunwind feature

perf can use either libdw or libunwind dwarf unwinders, or neither.
The perf-libunwind feature implies that if disabled, neither should be
used, so have it disable both libdw and libunwind DWARF unwinders if
disabled.

This fixes [YOCTO #7129].
