[PATCH] use --hostonly-i18n for dracut

[Tong Li]

Resolves: bz1411240
Use --hostonly-i18n to force dracut to install only needed
keyboard and font files according to host's configuration, which
reduced initramfs's size by 2M on F25 x86_64.

Is it the compressed size? The size we cared is the uncompressed size
because in 2nd kernel they will be uncompressed in ram.

Yes, it was compressed size. The option reduced the size of
uncompressed initramfs by about 5M.

Not sure if we even need local i18n, can we only support "English" environment?
For example, I added "-o i18n" instead, and it seems work properly on my zh_CN.UTF-8 environment.

Probably can't. Customers require local env, there's a zanata which is a
project to do the translation, we ever were tortured by the process.

Hmm, the translation is previously for the firstboot module which is
used for the installation gui. The i18n dracut module is different, is
is more for console fonts and kbd settings.

There was a bug before in RHEL6 about font missing, later we added
console font to fix it, just search git log about below subject:
"add default console font"

So it depends on user setting about locale, maybe default UTF8 setup is
fine without i18n module, but we are not sure it works with all setup..

Another thing is keyboard map, without correct keyboard map, one can not
input correctly in kdump default shell. There are various keyboard
layout besides of en

Will change the size to uncompressed size when applying.
