build-sys: fix out-of-tree build for hwclock

The file sys-utils/hwclock-parse-date.c is generated from .y and
stored in the build directory and "#include hwclock.h" is interpreted
relatively to the build tree rather than to source tree. We need
explicit -I compiler option to point to $srcdir for hwclock.
