Bug Description

When using relative path with incremental backup. Xtrabackup fails to read xtrabackup_checkpoint file and it exit with error. That's how I reproduced it.

# xtrabackup --version
xtrabackup version 2.2.13 based on MySQL server 5.6.24 Linux (x86_64) (revision id: 70f4be3)

FULL BACKUP:
# innobackupex --no-timestamp backup/full/

innobackupex: Using server version 5.6.29-76.2

161118 11:16:11 innobackupex: completed OK!

INCREMENTAL BACKUP:
# innobackupex --no-timestamp --incremental ~/backup/inc_1 --incremental-basedir=~/backup/full
.
.
innobackupex: Using server version 5.6.29-76.2

innobackupex: Created backup directory /root/backup/inc_1

innobackupex: Waiting for ibbackup (pid=1802) to suspend
innobackupex: Suspend file '/root/backup/inc_1/xtrabackup_suspended_1'

xtrabackup: Error: cannot open ~/backup/full/xtrabackup_checkpoints
xtrabackup: error: failed to read metadata from ~/backup/full/xtrabackup_checkpoints
innobackupex: got a fatal error with the following stacktrace: at /usr/bin/innobackupex line 2711

 main::backup() called at /usr/bin/innobackupex line 1609
innobackupex: Error: The xtrabackup child process has died at /usr/bin/innobackupex line 2711.

As soon as I use absolute path i.e. /root/backup/inc1/ for --incremental and /root/backup/full/ for --incremental-basedir options for incremental backup it completes without any errors.
