selftests/bpf: Fix pkg-config call building sign-file

[ Upstream commit 5f5486b620cd43b16a1787ef92b9bc21bd72ef2e ]

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.
