jextract expects full or relative path for each header file in command line. When user has to specify -I options, we sometimes have to repeat path specified in -I for header files as well.

Example:

jextract -I /usr/local/include /usr/local/include/foo.h

It'd nice to be able to specify:

jextract -I /usr/local/include foo.h

If there is 'foo.h' in current directory jextract can search foo.h in each of the -I value specified and pick the first such header available.
