[3.9] gh-109396: Fix test_socket.test_hmac_sha1() in FIPS mode (GH-109423) (GH-125107)

Use a longer key: FIPS mode requires at least of at least 112 bits.
The previous key was only 32 bits.

(cherry picked from commit e091b9f20fa8e409003af79f3c468b8225e6dcd3)
(cherry picked from commit f7bfac4b3dd30920f97a542fd78c355ce62aa267)
