fix(master-link): Rename RPCD to luci.master_link and flatten JSON output

Hyphens in RPCD filenames break ubus CLI argument parsing. Rename
luci.master-link to luci.master_link and update all references in
the JS view, ACL, and Makefile. Also pipe RPCD method output through
tr -d '\n\t' so ubus receives single-line JSON it can parse.
