fetch-pack: drop static advertise_sid variable 

write_fetch_command_and_capabilities() is moved to 'connect.c' in a
subsequent commit. To prepare for that, drop the static variable usage
of advertise_sid. Currently advertise_sid is used in two places:

1. In function do_fetch_pack():
        if (!server_supports("session-id"))
               advertise_sid = 0;

2. In function fetch_pack_config():
        repo_config_get_bool("transfer.advertisesid", &advertise_sid);

About 1, it is only relevant for v0/v1 protocol, move it into
find_common().

About 2, call repo_config_get_bool() inside of
write_fetch_command_and_capabilities() and find_common() replacing the
static variable.

Because repo_config_get_bool() leaves advertise_sid as is if it is not
set, initialize it to 0 matching its default.
