[llvm-readobj][test] - Cleanup the many-sections.s test case.

[grimar]

Summary

It removes 2 precompiled binaries used which are now
can be crafted with the use of yaml2obj.

LGTM.

-## many-sections.elf-x86_64 is a file that was generated to simulate
-## an object with more than ~65k sections. When an ELF object
-## has SHN_LORESERVE (0xff00) or more sections, its e_shnum field
+## Here we simulate an object with more than ~65k sections and check how we dump it.
+## When an ELF object has SHN_LORESERVE (0xff00) or more sections, its e_shnum field
 ## should be zero and sh_size of the section header at index 0 is used
 ## to store the value. If the section name string table section index is
 ## greater than or equal to SHN_LORESERVE, then e_shstrndx field
 ## should have the value of SHN_XINDEX and sh_link of the section header
 ## at index 0 is used to store the value.
-##
-## many-sections.elf-x86_64 has few sections to save disk
-## space, but its e_shnum, e_shstrndx, sh_size and sh_link fields are set
-## according to the above description, so that we can test the dumper.
