E2E: Cleanup emulator variable

We are now specifying the BMC protocol directly and do not need to
expose the emulator variable. The emulator will be picked based on
the protocol.

 # Description: This script sets up the environment and runs E2E tests for the
 #              BMO project. It uses either vbmc or sushy-tools based on
-#              the BMO_E2E_EMULATOR environment variable.
-#              With sushy-tools, it is also possible to choose between
-#              redfish-virtualmedia and redfish protocols using the
-#              SUSHY_TOOLS_PROTOCOL environment variable.
-#              By default, sushy-tools and redfish-virtualmedia will be used.
-# Usage:       export BMO_E2E_EMULATOR="vbmc"  # Or "sushy-tools"
+#              the BMC_PROTOCOL environment variable.
+#              Supported protocols are: ipmi, redfish and redfish-virtualmedia.
+#              VBMC is used for ipmi and sushy-tools for both redfish protocols.
+#              By default, redfish-virtualmedia will be used.
