Several BCC bio tools are broken due to kernel change ([0]).
blk_account_io_{start, done} were renamed to __blk_account_io_{start, done},
and the symbols gone from /proc/kallsyms. Fix them by checking symbol existence.

Kernel commit 24b83deb29b ("block: move struct request to blk-mq.h")
and be6bfe36db17 ("block: inline hot paths of blk_account_io_*()")
introduce changes which break disksnoop.
Like iovisor#3748 and iovisor#3877 but for disksnoop, this commit fixes those issues.
Closes iovisor#3825.
