libfec: pack the fec_header structure
The fec_header structure is generated build time and stored on disk.
The fec_header might be build on a 64 bits machine while it is read
per a 32 bits device or the other way around. In such situations, the
fec_header fields are not aligned as expected by the device and it
fails to read the fec_header structure.
This patch makes the fec_header packed.
