Switch from SIGNATURE_RSA to SIGNATURE_HMAC_SHA1 (pycontribs#1643)

Switch from SIGNATURE_RSA to SIGNATURE_RSA_HMAC_SHA1

RHEL 9 has a policy of deprecating SHA1 and has removed it from
python-oauthlib via the addition of locally added patch.

Switching to SIGNATURE_RSA_HMAC_SHA1 allows this module to be used
on RHEL9 when the system package python3-oauthlib-3.1.1-2.el9.noarch.rpm
is used.
