[PATCH] posix: execvpe: skip $PATH components that are too long

[Pádraig Brady]

* posix/execvpe.c (__execvpe_common): Rather than error out
with ENAMETOOLONG, just ignore and try the next path.
Note we know the FILE length is <= NAME_MAX, so the ENAMETOOLONG
almost certainly pertains to the current $PATH entry.
