[PATCH] Display key UIDs in key listing even when --fast-list-mode is set.

[Guilhem Moulin]

As it's already the done for --edit-key:

  $ gpg --with-colons --fast-list-mode --edit-key $KEYID quit

This makes --fast-list-mode useful together with --list-sigs, as it's
shows on which UID the certificate signatures are added.

Using --fast-list-mode with --list-sigs can make the command
tremendously faster on large keyrings when the listed key(s) contains
many signatures.

Printing the key UIDs does not seem to add any significant performance
penalty to the old behavior of --fast-list-mode.  This is not surprising
since UID packets are part of the OpenPGP Public-Key packet hence are
encountered during the listing anyway; printing the text doesn't require
extra lookup in the keyring (unlike displaying the primary UID of the
signing keys) or otherwise expensive computation (unlike trust or
validity calculation).
