When selecting which memory region of a TA should be hashed, exclude
those without VM_FLAG_READONLY in their flag field instead of requiring
the absence of TEE_MATTR_UW in attr. This makes the code more
consistent and fixes an issue triggered by commit 52e7b1a67f8f ("core:
use user-access functions in ldelf interaction"). With that commit, an
additional region is mapped read-only (i.e., no TEE_MATTR_UW) but does
not have a fixed content for the TA. It can be excluded easily since it
does not have the VM_FLAG_READONLY flag.
