Fix waiting for ustd on shutdown
When starting the daemon use a fifo instead of a pidfile. Otherwise the start
races against the reading of the pidfile. During shutdown we should wait for
all the existing background shells (there is only one) instead of waiting
for the pid of the daemon process.

The race was that usttrace waited for 0.5s for the daemon (started in

Now, it is guaranteed to succeed.

minor refactor of ustd to avoid deadlock
Previously, we could have a deadlock between ustd and libust:
- libust connects to the ustd socket and waits for a reply
- while ustd is sending commands to the same libust to get
information about a buffer
To fix this, info about a buffer to collect is retrieved from within
a different thread than the one that processes incoming commands.
