debuginfod: sqlite3 metrics
Add metrics for tracking sqlite3 error counts and query performance.
The former looks like a new sibling of the "error_count" family, and
is tested by dd-corrupting a live database file then triggering some
debuginfod activity.
error_count{sqlite3="file is not a database"} 1
The latter looks like _count/_sum pairs for each type of sqlite
prepared-statement used in the code, and is grep smoke-tested. They
should assist a sysadmin in tuning db storage. This example shows a
6.4 ms/operation cost:
sqlite3_milliseconds_count{step-done="rpm-file-intern"} 318
sqlite3_milliseconds_sum{reset="rpm-file-intern"} 2033
