boost: Use PARALLEL_MAKE for bjam 

Like make, bjam accepts the parameter -jX for multithreaded execution
do_install also profits from this setting
Tested with a quad core 64bit intel cpu (with hyperthreading) PARALLEL_MAKE="j16"

$ time bitbake boost

before:
real    14m37.433s
user    7m40.785s
sys     4m30.109s

after:
real    7m11.979s
user    12m10.694s
sys     2m47.078s

Also fixes tab indention
