runtime(bitbake): support forward-slashes in bitbake varflags

Enable syntax highlighting for forward-slashes in Bitbake variables with
varflags. Bitbake allows for forward-slashes in both the variable name
and their potential varflags. E.g. the following should match:

FOO_BAR[baz] = "foobar"
FOO_BAR_foo/bar[baz] = "foobar"
FOO_BAR_foo/bar[baz/bazzer] = "foobar"

Also allow plus-signs in variable names, to be in line with normal
variable names.
