perf symbol-elf: Add support for the block argument for libbfd

James Clark caught that the BUILD_NONDISTRO=1 build with libbfd was
broken due to an update to the read_build_id function adding a
blocking argument. Add support for this argument by first opening the
file blocking or non-blocking, then switching from bfd_openr to
bfd_fdopenr and passing the opened fd. bfd_fdopenr closes the fd on
error and when bfd_close are called.
