    readelf: display dynamic symtab without section headers

    This commit adds a new option "-D/--use-dynamic" to support printing the
    dynamic symbol table from the PT_DYNAMIC segment. By using the
    PT_DYNAMIC segment, eu-readelf can go through the contents of dynamic
    section entries and the values of each tag. From that, we can get the
    address and size of the dynamic symbol table, the address of the string
    table, etc.

    By using the new option "-D/--use-dynamic", eu-readelf can list the
    symbols without section headers.

    Example:
      $ ./src/readelf -Ds a.out
          0: 0000000000000000      0 NOTYPE  LOCAL  DEFAULT    UNDEF
          1: 0000000000000000      0 FUNC    GLOBAL DEFAULT    UNDEF
__libc_start_main@GLIBC_2.34 (2)
          2: 0000000000000000      0 NOTYPE  WEAK   DEFAULT    UNDEF
__gmon_start__
