rS349730: elfcopy: Clear errors after fetching the shstrtab index.

Summary

Otherwise a future call to elf_errno() will return a non-zero value.
update_shdr(), for example, treats any errors associated with the ELF
descriptor as fatal. Clear the error per the first example in
elf_errmsg.3.

Convert to elf_getshdrstrndx() while here since elf_getshstrndx() is
apparently deprecated.
