use the phony module name to install org.apache.http.legacy

org.apache.http.legacy.boot which is the runtime library for
org.apache.http.legacy API is now renamed to org.apache.http.legacy.impl
as a result of migration to java_sdk_library.

Installing the runtime library can now be done via the sdk lib name
(org.apache.http.legacy) which internally includes the .impl runtime
lib.

Bug: 77577799
Test: m -j
Test: device boots to the UI. No error related to org.apache.http.legacy
shown in the logcat log.
Test: adb shell cmd package list libraries | grep http shows the
library.
