Suppress the info messages while installing Boost (#1349)

Suppressed the info messages e.g. file copy info logs, while installing
Boost. Default prints too many logs.

./b2 --help-options
...
* -dn; Enables output of diagnostic messages. The debug level 'n' and
all below it are enabled by this option.
* -d+n; Enables output of diagnostic messages. Only the output for debug
level 'n' is enabled.

Debug Levels:

Each debug level shows a different set of information. Usually with
higher
levels producing more verbose information. The following levels are
supported:

  * 0; Turn off all diagnostic output. Only errors are reported.
* 1; Show the actions taken for building targets, as they are executed.
* 2; Show quiet actions and display all action text, as they are
executed.
  * 3; Show dependency analysis, and target/source timestamps/paths.
  * 4; Show arguments of shell invocations.
  * 5; Show rule invocations and variable expansions.
* 6; Show directory/header file/archive scans, and attempts at binding
to targets.
  * 7; Show variable settings.
* 8; Show variable fetches, variable expansions, and evaluation of 'if'
expressions.
  * 9; Show variable manipulation, scanner tokens, and memory usage.
  * 10; Show execution times for rules.
  * 11; Show parsing progress of Jamfiles.
  * 12; Show graph for target dependencies.
  * 13; Show changes in target status (fate).
