Hojun-Cho cd11d6e573 ww: driver/coordinator robustness — dirent errors, EINTR, block comments ...

Three same-cluster robustness holes. enumeratedir treated a failed
getdents64 (r<0) as EOF: a mid-walk error silently truncated the
package source list, and a first-read error was misdiagnosed as
"directory contains no WW package sources" -- it now routes the
caller's "cannot read directory" arm. run_test_bin's waitpid had no
EINTR retry and its return was unchecked, so an interrupted wait
left status==0 and reported a false test PASS (the do_run twin
already retried). The coordinator's pkgskipspace now also skips
/* */ before the package clause like the driver's sep_skip_space --
a source opening with a block comment built under ww but failed
coordinator discovery.
