configure: Drop unused AC_PROG_CPP
In configure, we were calling `AC_PROG_CPP` but never making use of the
$CPP variable it sets or reads.
The issue is $CPP will show up in the --help output of configure,
falsely advertising a configuration option that does nothing.
The reason we don't use the $CPP variable is because HS_CPP_CMD is
expected to be a single command (without flags), but AC_PROG_CPP, when
CPP is unset, will set said variable to something like `/usr/bin/gcc -E`.
Instead, we configure HS_CPP_CMD through $CC.
