CI: Introduce Smatch for static analysis (#125)
Smatch[1][2] is a pluggable static analysis for C. It may help us find
out the potential problem of the example code.

Doing with smatch, if set the --file-output flag, it will generate the
{}.c.smatch report for each c file. This will make a little bit
complicated to collect all the report messages. So, here we stay at the
default setting, stdout for the smatch messages.

For more information, see:

- https://elinux.org/images/d/d3/Bargmann.pdf

Also, fix the warning from Smatch:

Smatch failed: 1 warning(s), 1 error(s)
lkmpg/examples/procfs2.c:57 procfile_write() error: buffer overflow 'procfs_buffer' 1024 <= 1024
lkmpg/examples/kbleds.c:58 kbleds_init() warn: argument 5 to %lx specifier is cast from pointer

Furthermore, the effect of the write operation in procfs2.c is too
implied. So after writing, print the buffer every time.

Close #122
