Fix the RPM SPEC files for beta and unstable packages

Before this change the beta and unstable rpm packages were without an icon as
both were correctly specifying the correct name in desktop file
(Icon=google-chrome-beta resp. Icon=google-chrome-unstable) but icon with that
name was never installed.

As a consequence installing the Chrome stable and beta rpm packages and later
removing the beta package would remove the icon and left the stable installation
without any (as both were using the same name without channel: google-chrome).

To fix the issue we need to define the PACKAGE variable in rpm/build.sh the same
way as in debian/build.sh so when we start to process the postinst.include
template (that is included from chrome.spec.template) the PACKAGE variables is
replaced with correct value (google-chrome for stable otherwise
google-chrome-beta or google-chrome-unstable) on not just google-chrome for all
channels as previously.

Also replace the PACKAGE_FILENAME usages in rpm/chrome.spec.template with
PACKAGE when it finally contains the right value and use the PACKAGE_FILENAME
just to specify the package name (where the channel is suffixed in the name even
for the stable channel).
