logind,machined: bump TasksMax=

Issue #2388 suggests the current TasksMax= setting for user processes is to low. Bump it to 12K. Also, bump the
container TasksMax= from 8K to 16K, so that it remains higher than the one for user processes.

(Compare: the kernel default limit for processes system-wide is 32K).

Fixes #2388
