    pack.c: avoid returning uninitialized String
    
    Fix unpacking with 'b', 'B', 'h' and 'H' format. Do not return an
    uninitialized String to Ruby before filling the content bytes.
    Fixes r11175 ("pack.c (pack_unpack): execute block if given with
    unpacked value instead of creating an array", 2006-10-15).
    [ruby-core:78841] [Bug #13075]
    test/ruby/test_pack.rb: fix test case added by r57187
    
    The test case for String#unpack added by r57187 is not properly testing
    because the String will be filled after the block invocation.
