SELinux has a separate file mmap permission in 4.14+ kernels. Add this
to dexoptanalyzer(d) in cases where it could already access files (in
particular, secondary dex files).

Addresses denials of the form:

  avc: denied { map } for […] path="/data/data/[…]" […]
  scontext=u:r:dexoptanalyzer:s0 tcontext=u:object_r:app_data_file:s0

Test: Reproduce steps in bug 138683603 on a device with a 4.14+ kernel
      and check the absence of SELinux denials
Bug: 138683603
