[MC][ELF] Mark Solaris objects as ELFOSABI_SOLARIS

rorth · rorth · commit 8738c5b0fe0a · 2021-08-13T14:31:32.000+02:00
Prompted by D107747 <https://reviews.llvm.org/D107747>, it seems prudent to mark objects as `ELFOSABI_SOLARIS` on Solaris. Tested on `amd64-pc-solaris2.11`, `sparcv9-sun-solaris2.11`, and `x86_64-pc-linux-gnu`. Differential Revision: https://reviews.llvm.org/D107748
