Get the rvm GPG key via curl from the rvm web side instead of via hkp.

Rationale: hkp is less reliable if installation is behind a firewall,
and the installer might still work even if RVM changes its key.

FWIW: The previous code no longer works, as gpg nowadays requires a
"0x" prefix in front of the fingerprint.
