The virtual-locale-* packages are provided by libc which may or
may not have a matching locale for any given recipes's provided locales.
Certainly, we shouldn't get a failure if the locale package isn't
available.
This patch therefore makes the dependency optional rather than
required, allowing the locale packages in question to install. This
resolves errors like:
virtual-locale-eo is needed by bash-locale-eo-4.2-r5.i586
virtual-locale-en+boldquot is needed by bash-locale-en+boldquot-4.2-r5.i586
virtual-locale-en+quot is needed by bash-locale-en+quot-4.2-r5.i586
