[PATCH bpf] selftests/bpf: fix pkg-config call building sign-file

When building sign-file, the call to get the CFLAGS for libcrypto is missing white-space between `pkg-config` and `--cflags`:

$(shell $(HOSTPKG_CONFIG)--cflags libcrypto 2> /dev/null)

Removing the redirection of stderr, we see:

$ make -C tools/testing/selftests/bpf sign-file make: Entering directory '[...]/tools/testing/selftests/bpf' make: pkg-config--cflags: No such file or directory SIGN-FILE sign-file make: Leaving directory '[...]/tools/testing/selftests/bpf'

Add the missing space.
