Decrease logspam of stack MTE remapping.
Currently the log is called for each library that's loaded with MTE
stack. For apps that are a launched with stack MTE (e.g. the CTS test
apps), this causes ~40 or so loglines telling us that the stack is being
remapped.
Instead, make it log only once, the first time it's remapped.
Bug: N/A
Test: blatant visual code inspection
