system_server: support hard linking for split APKs

Commit 85ce2c706e95f96c95b3af418b7bda0bfe9918f4 removed hard link
support from create_file_perms, but system_server requires hard
link support for split APKs. Allow it.

Addresses the following denial:

  audit(0.0:152): avc: denied { link } for name="base.apk" dev="dm-0" ino=816009 scontext=u:r:system_server:s0 tcontext=u:object_r:apk_data_file:s0 tclass=file permissive=0

Steps to reproduce:
1) Find the directory "hellogoogle3.splitapk"
2) adb install-multiple -r hellogoogle3_incremental.apk
3) adb install-multiple -r -p com.google.android.samples.hellogoogle3 native.apk

Expected:
  2nd APK installs successfully.

Actual:
  2nd APK fails to install.
