Replace #include serial.h with iofunc.h

According to iwyu, to avoid unecessary rebuilds and to reduce the
chances of breakages of the build if includes are rearranged, the
code that uses serial_open() and ser_close() should include
serial.h while the code that uses read_block() write_block() and
similar should include iofunc.h, code that uses all of them should
include both files.

Found with iwyu.
