Fixes <https://bugs.gnu.org/35341>.
Reported by Florian Pelz <pelzflorian@pelzflorian.de>.
Previously, we'd call 'ensure-default-profile' before the connection to
the daemon has been opened. On the first connection, the daemon ensures
that /var/guix/profiles/per-user is world-writable. Since we were
calling 'ensure-default-profile' before that,
/var/guix/profiles/per-user was typically non-writable (555 and
root-owned), and thus 'guix pull' would error out.
* guix/scripts/pull.scm (guix-pull): Call 'ensure-default-profile'
within 'with-store'.
