[llvm-readobj] Print section type values for unknown sections.

Description

[llvm-readobj] Print section type values for unknown sections.

Summary:
This patch displays a hexadecimal section value (Elf_Shdr::sh_type) or section-relative offset when printing unknown sections.

Here is a subset of the output (ignoring the fields following "Type" when dumping an ELF's GNU --section-headers table).
Section Headers:

[Nr] Name              Type
[16] android_rel       LOOS+0x1
[17] android_rela      LOOS+0x2
[27] unknown           0x1000: <unknown>
[28] loos              LOOS+0
[30] hios              VERSYM
[31] loproc            LOPROC+0
[33] hiproc            LOPROC+0xFFFFFFF
[34] louser            LOUSER+0
[36] hiuser            LOUSER+0x7FFFFFFF

As a comparison, the previous output looked something like the above, but with a blank "Type" field:

[Nr] Name              Type
[27] unknown
[28] loos
[30] hios              VERSYM
[31] loproc
[33] hiproc
[34] louser
[36] hiuser
