Do not get 'generation' using ioctl when evm_portable is true

If a signatures is detected as being portable do not attempt to read the
generation with the ioctl since in some cases this may not be supported
by the filesystem and is also not needed for computing a portable
signature.

This avoids the current work-around of passing --generation 0 when the
ioctl is not supported by the filesystem.
