[PATCH] perf tools: Add gtk.<command> config option for launching GTK browser

[Namhyung Kim <namhyung@kernel.org>]

From: Namhyung Kim <namhyung.kim@lge.com>

Add config option for launching GTK browser for the specified command
by default.  Currently only 'report' command is supported.

Adding following line to the perfconfig file will have a same effect
of specifying --gtk option on command line (unless other related
options are not given).

$ cat ~/.perfconfig
[gtk]
report = true
