perf tools: Initialize perf_data_file fd field

Building the perf CTF converter fails with gcc 4.8.4 on Ubuntu 14.04
with the following error:

  error: missing initializer for field âfdâ of âstruct perf_data_fileâ
  [-Werror=missing-field-initializers]

Per 4b838b0db4e9 ("perf tools: Add compression id into 'struct
kmod_path'") and the ensuing discussion on the mailing list, it appears
that this affects other distributions and gcc versions.
