[PATCH 04/12] selftests: android: ion: Fix ionmap_test dependencies

[Geert Uytterhoeven]

When building kselftest in a separate output directory:

    /tmp/cc44s4yX.o: In function `socket_send_fd':
    tools/testing/selftests/android/ion/ionutils.c:221: undefined reference to `sendtosocket'
    /tmp/cc44s4yX.o: In function `socket_receive_fd':
    tools/testing/selftests/android/ion/ionutils.c:243: undefined reference to `receivefromsocket'

The dependencies for the various test programs are expressed twice:
  1. Once using $(TEST_GEN_FILES), which supports building in the source
     directory only,
  2. A second time using $(OUTPUT), which supports building in either
     the source or build directory, but lacks a dependency of
     ionmap_test on ipcsocket, causing the link error above.

Fix this by:
  - Adding the missing dependency to 2,
  - Dropping superfluous rule 1.

Remove the "all" target while at it, as that is already handled by the
included lib.mk.
