binder: don't log on EINTR

binder_wait_for_work used to return -ERESTARTSYS if interrupted by a
signal. This error wasn't logged to avoid spamming the console. After
the return value changed to -EINTR to better conform to the kernel API,
the logging portion wasn't modified.

Filter EINTR from binder error logs.

Test: verified that the console isn't spammed anymore
