Set errno to ENOMEM when simulating a malloc failure.

Per malloc(3):

    The  UNIX  98  standard requires malloc(), calloc(), and realloc() to set
    errno to ENOMEM upon failure.  Glibc assumes that this is done (and the
    glibc versions of these routines do this); if you use a private malloc
    implementation that does not set errno, then certain library routines may
    fail without having a reason in errno.

Notably, thread_test otherwise fails an assertion deep in glibc.
