parse load_offset (bias) of restore command as long

Following failures are noticed for avr-gdb. This may be the case
for targets like AVR which has integer_to_address hook defined.

FAIL: gdb.base/dump.exp: struct copy, srec; value restored ok
FAIL: gdb.base/dump.exp: struct copy, ihex; value restored ok
FAIL: gdb.base/dump.exp: struct copy, tekhex; value restored ok

These tests are failed because load_offset(bias) of restore command
parsed as address.

command: restore filename [binary] bias start end

Except binary, other BFDs have a built-in location; gdb restores content
at offset 'bias' from that location. So, 'bias' of 'restore' command should
be parsed as address only when the file is binary.

Below patch changes gdb to parse 'bias' as long if the file is not binary.
