    Fix debug link crc reading
    
    Debug link crc values is strored after null terminated string in 4
    aligned offset. But sysprof was only taking into accoutn alignment
    that made elf parser read wrong crc from the debug link string.
    
    Fix is simple check for string length and adding the length to offset
    before alignment.
