IMPALA-15064: Fix flakiness of 
test_query_profile_contains_query_compilation_metadata_load_events

This tests invalidates a table, runs a select query, and checks that
the runtime profile contains a set of static lines.
Some of these lines (e.g. CatalogFetch.RPCs.Bytes) are only included,
with local catalog, if the table is still evicted from the cache.
However, with it running parallelly with other tests, another query can
fetch the table, between the invalidate and the select query, making the
test fail.

Fixed by using a unique database in this test instead of a common one.
