Meck doesn't support modules built with '+deterministic' compile option

[nablaa]

Running meck against modules built with +deterministic compile option fails with the following stacktrace:

::{function_clause,[{lists,'-filter/2-lc$^0/1-0-',
                           [undefined],
                           [{file,"lists.erl"},{line,1286}]},
                    {meck_proc,backup_original,3,
                               [{file,"/home/foobar/meck/_build/default/lib/meck/src/meck_proc.erl"},
                                {line,361}]},
                    {meck_proc,init,1,
                               [{file,"/home/foobar/meck/_build/default/lib/meck/src/meck_proc.erl"},
                                {line,206}]},
                    {gen_server,init_it,2,
                                [{file,"gen_server.erl"},{line,365}]},
                    {gen_server,init_it,6,[{file,[...]},{line,...}]},
                    {proc_lib,init_p_do_apply,3,[{file,...},{...}]}]}

This is caused by the fact that the module doesn't have compile options in module_info/1:

$ cat foo.erl
-module(foo).
$ erlc foo.erl
$ erl -noshell -eval 'io:format("~p~n", [foo:module_info(compile)])' -run init stop
[{options,[]},
{version,"7.1.1"},
{source,"/home/foobar/foo.erl"}]
$ rm foo.beam
$ erlc +deterministic foo.erl
$ erl -noshell -eval 'io:format("~p~n", [foo:module_info(compile)])' -run init stop
[{version,"7.1.1"}]

Reproduction Steps

Run meck against modules built with +deterministic option.

Expected behavior

Meck should run against modules built with +deterministic.
