[PATCH v2 4/5] tests/init.sh: use != test operator instead of -ne

[Masatake YAMATO]

In get_config_option(), -ne operator was used to
compare the value extracted from config.h with 0.

Using -ne makes sense if OPTION is defined with "#define".  However,
if it is not defined or explictly undefined with "#undef", an empty
string is passed to -ne as left side operand. This causes an error
in dash and bash:

    % dash
    $ [ -n '' -a '' -ne 0 ]
    dash: 1: [: Illegal number:

    % bash
    $ [ -n '' -a '' -ne 0 ]
    bash: [: : integer expression expected

* tests/init.sh (get_config_option): Use != operand instead of -ne
operator.
