Building firefox on 2015Q1 with fixes

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

I just built Firefox 36 from 2015Q1 and ran into a pair of problems:
 
1) JPEG_DEFAULT=libjpeg-turbo in mk.conf seems required, otherwise 
configure will complain 

I suspect this is because we have in pkgsrc/www/firefox/mozilla-common.mk:
CONFIGURE_ARGS+=        --disable-libjpeg-turbo

While the configure script uses --enable-libjpeg_turbo (note the underscore
instead of the dash).

2) I had to apply this patch to build because pthread_condattr_setclock()
is not defined:

   pthread_condattr_t attrs;
   rv = pthread_condattr_init(&attrs);
   DCHECK_EQ(0, rv);
   pthread_condattr_setclock(&attrs, CLOCK_MONOTONIC);
