User has reported `dex2oat` failure with SELinux log:
```
W dex2oat64: type=1400 audit(0.0:922): avc: denied { read } for path="/data/adb/modules/zygisk_lsposed/bin/liboat_hook64.so" dev="dm-58" ino=91204 scontext=u:r:dex2oat:s0 tcontext=u:object_r:adb_data_file:s0 tclass=file permissive=0
```
Hence, we now set the SELinux context of `liboat_hook.so` in Dex2OatService.
Moreover, by the pull-request #194, we have to move `putenv` out of the if block by testing.
Indeed, if we call `putenv` inside the if block, then it is no longer valid out of the block.
