Fix parsing of backtick-enclosed table options

MariaDB encloses some table options in backticks by default
(e.g. `PAGE_COMPRESSED`=1). The option name lookup in
OptionsArrays::parse() used $token->token which includes the
backticks, causing the match against the options array to fail.

This adds a targeted check: when a backtick-enclosed symbol is
followed by '=', its unquoted value is used for the lookup.
A lookahead for '=' prevents regular quoted identifiers (such as
table or column names) from being mistaken for options.

Fixes #643
