docker-php-ext-install cpu core number option

[soullivaneuh]

Would be very nice to add an option on docker-php-ext-install command to set the number of cpu core to use.

That would be transmitted to the make command.

Ex: make -j5

For the others that want this feature, I found a little sed trick to put on your Dockerfile:

RUN sed -i 's/make$/make -j`nproc`/' /usr/local/bin/docker-php-ext-install && \
docker-php-ext-install \
zip \
pdo \
pdo_mysql \
intl \
gd \
pcntl \
bcmath \
shmop \
mbstring

I earn 45 seconds on my image build with -j8.
