Ian Rogers ca81e74dc3 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.

Reported-by: James Clark <james.clark@linaro.org>
Closes: https://lore.kernel.org/lkml/20250903-james-perf-read-build-id-fix-v1-2-6a694d0a980f@linaro.org/
Fixes: 2c369d91d0 ("perf symbol: Add blocking argument to filename__read_build_id")
