[PATCH] font-util: Add a shorthand --disable-all-encodings option.

[Michał Górny]

This option is useful to disable all possible font encodings at once,
without fine-graining the calling ebuilds for a list of encodings
supported by each font package.

The option is parsed before all other encoding options, so it basically
sets defaults for all of them. Afterwards, any encoding can be
re-enabled back using '--enable-<encoding>' (much like
'--disable-all-encodings --enable-iso8859-2').
