btrfs: Update quick and auto tag for btrfs group

Update the following quick/auto tag based on their execution time

btrfs/007
btrfs/050
btrfs/100
btrfs/101

Two systems are used to determine their execution time.  One is
backed by an SATA spinning rust, whose maximum R/W speed is about
100MB/s, modern desktop performance. (VM1)

Another one is a VM inside a openstack pool, with stronger CPU and
memory performance along with high latency storage.  Maximum R/W
speed is around 150MB/s, latency is much higher than normal HDD
though. (VM2)

The 'quick' standard is a little more restrict, only when both
systems pass the test within 30s(+/- 10%), while 'auto' is less
restrict, any system can pass within 5min(+/- 10%) will still stay
in 'auto' group.

Other test cases don't fit both standards on both systems will not
be modified.

Execution time result: (Unit: seconds)
