Also check available in TZ timezone's constructor
Follow up to commit 00d9a9a9b59650b8e297f91dcc600c377da5bceb - as
commented in the QTZ constructor, one of the reasons for the prior "is
available" check was to avoid creating TZ cache entries for it; so
have the TZ backend also (like ICU) overtly check for availability
before trying to find data for the given ID. This duplicates work done
later in the constructor, which can perhaps be optimised out later,
but is no worse than where we were before the commit mentioned above.
Pick-to: 6.7 6.6 6.5
