[llvm-readobj][test] - Add a check for --dyn-syms.

Browse Source 
We have a `-dyn-symbols` option. It has a `--dyn-syms` alias
that is not tested in llvm-readobj tests currently.

There was a Object/readobj-elf-versioning.test where it is used,
but I've removed it in D73163. And also it is not the
right place to test it anyways.

## Case 2: Check the two-letter alias --dt is equivalent to the --dyn-symbols
## Case 2: Check the output for aliases.
## a) Check the two-letter alias --dt is equivalent to the --dyn-symbols
## full flag name.
# RUN: llvm-readobj --dt %t1.so > %t.readobj-dt-alias
# RUN: llvm-readobj --dyn-symbols %t1.so > %t.readobj-dt-no-alias
# RUN: cmp %t.readobj-dt-alias %t.readobj-dt-no-alias
## b) Check --dyn-syms equals --dyn-symbols, --dt for llvm-readobj.
# RUN: llvm-readobj --dyn-syms %t1.so > %t.readobj-dyn-syms
# RUN: cmp %t.readobj-dt-alias %t.readobj-dyn-syms
## c) Check --dyn-syms equals --dyn-symbols for llvm-readelf.
# RUN: llvm-readelf --dyn-syms %t1.so > %t.readelf-dyn-syms
# RUN: llvm-readelf --dyn-symbols %t1.so > %t.readelf-dyn-symbols
# RUN: cmp %t.readelf-dyn-symbols %t.readelf-dyn-syms
## Case 3: Check that we are able to dump the dynamic symbol table even when we have no program headers.
## In this case we find the table by it's type (SHT_DYNSYM) and ignore the DT_SYMTAB value.
