Use unique error value in broker_process_unitetest.cc

Distinguish between the permission errors the broker process
fabricates vs. organically ocurring EPERM from a syscall.

Use block-scope rather than unique_ptrs to force broker destruction.

Fix a dubious use of ScopedFD(). ScopeFD's only legal bad FD value
is -1, which co-incidentally happens to be -EPERM.  So don't apply
this where we know the file is invalid, since other negative values
cause a CHECK().

Convert some ASSERTS to EXPECTS, to avoid crashes.
