[gold][arm]: Fix arm elf header flags wrt hardfp bit

[Han Shen]

Hi Cary, current gold does not set properly the hardfp bit for elf header flags.

In Target_arm::do_adjust_elf_header, both e_ident and e_flags are
modified, but only e_ident is put back to view, fixed by putting back
flags.

Test - build, and functional test (hardfp bit is properly set now)

gold/ChangeLog:
        * arm.cc (Target_arm::do_adjust_elf_header): Set flags into view.

Ok for trunk?
