test-merge-subrepos: make test compatible with chg
The test checks the output of '.hg/blackbox.log' which will contain
logs corresponding to chg in case chg is running. Therefore, this commit
modifies the test to take chg into consideration while checking the
blackbox.log contents.
Test Plan:
Ran the test 'test-merge-subrepos.t' with and without the '--chg'
option.

cHg
===
A fast client for Mercurial command server running on Unix.
Install:
$ make
$ make install
Usage:
$ chg help # show help of Mercurial
$ alias hg=chg # replace hg command
$ chg --kill-chg-daemon # terminate background server
Environment variables:
Although cHg tries to update environment variables, some of them cannot be
changed after spawning the server. The following variables are specially
handled:
* configuration files are reloaded automatically by default.
* CHGHG or HG specifies the path to the hg executable spawned as the
background command server.
The following variables are available for testing:
* CHGDEBUG enables debug messages.
* CHGSOCKNAME specifies the socket path of the background cmdserver.
* CHGTIMEOUT specifies how many seconds chg will wait before giving up
connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60
