ANDROID: Revert "arm: move ELF_ET_DYN_BASE to 4MB"
This ARM mmap change breaks AddressSanitizer:
Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
Revert it until ASAN runtime library is updated to handle it.
Bug: 67425063
This reverts commit d2471b5e84f32de4e09b58f5436a4ce3ee935e32.
