target/rd: Allow WriteCacheEnabled=1 operation with rd_mcp backends 



This patch adds the missing rd_mcp_template->write_cache_emulated=1 bit to
optionally allow WriteCacheEnabled=1 (WCE) to be enabled for the built-in
TCM/rd_mcp backend driver.

Tested on v3.6-rc[0,2] code with loopback+tcm_vhost fabric ports.
