 prevent empty trigger functions to be optimized away with -o2 (#218)

cause function calls to be optimized away, although the function call is
live. To keep such calls from being optimized away, put asm ("");'

 detect kernel headers even if they are splitted into source/ and
 build/ directories

Currently bpftrace uses only /lib/modules/`uname -r`/source/ if it
exists. This however leads to failures Debian where generated kernel
headers, such as include/generated/autoconf.h are put into a separate
directory, for example:
