Android: Valgrind: Analyzing on device

Steps to reproduce:

• create a widget application from template
• select an android kit
• start analyzing using Memcheck or Callgrind

Current result:

• I didn't get anything
• cannot stop valgrind [Stop button does not help, closing Application Output pane neither]
• had to restart QC to get a valid state for valgrind

Note: Not sure if this should work at all.. But I get something more using a Desktop kit. [more == I get an error as I'm stuck on valgrind 3.13 on macOS]
