Fix file_contexts for flattened apexes
APEX modules can be configured with apex_name and file_contexts
properties.
- apex_name overrides the activation point
for example, if apex_name is 'foo', it will be flattened under
/system/apex/foo even if its name is 'bar'.
- file_contexts overrides file_contexts filename
for example, it file_contexts is 'foo',
/system/sepolicy/apex/foo-file_contexts should be used even if its
name is 'bar'.
Previously, file_contexts files for flattened apexes are assumed to have
names like "/system/sepolicy/apex/<apex_name>-file_contexts". But, as
described above, calculating <apex_name> from file entries might be
wrong
Now, it relies on Soong's makevar APEX_FILE_CONTEXTS_INFOS which is list of
<apex_name>:<file_contexts> pairs.
