ftrace: Update ftrace event regex

The regex used for the parsing of ftrace events proved inadequate for
parsing certain events, namely those that started with opening
parentheses, as described in issue #239.

The solution is an update to the regex which I have attempted to verify
using regex101 in Java mode.

Fixes: #239
