Kamil Rytarowski aee7b0f209 wrong usages of sem_open in the libFuzzer
Summary:
Fixed two non-standard usages of sem_open in the libFuzzer library and
one NetBSD-related modification with test script.


  - The return value to indicate error should be SEM_FAILED instead of
    (void *)-1 (please refer to "RETURN VALUE" section in this [[
    http://pubs.opengroup.org/onlinepubs/9699919799/functions/sem_open.html
    | page ]]). Actually, SEM_FAILED != (void *)-1 holds in NetBSD.

  - The SharedMemoryRegion::SemName function should return name
    starting with slash. Because the behaviour of name which does not
    start with slash is unspecified as the [[
    http://pubs.opengroup.org/onlinepubs/9699919799/functions/sem_open.html
    | "DESCRIPTION" section ]] specified:

> If name does not begin with the <slash> character, the effect is implementation-defined.

  - The length of name is limited to 14 in NetBSD, it is suggested to
    reduce the length of equivalence server name in the test script.
