Currently llvm-readobj prints e_entry address in uppercase mode, however all other places such as 'symbols', 'relocs', the addresses are printed in lowercase mode. This PR aims to print the addresses in uniform manner.

Other use-case:
FileCheck comparison is case-sensitive by default, so if you would like to compare e_entry address with the same address in the symbol table it won't match by default.
