Adjust timeouts for invoked processes

[asgrim]

Fixes#72

Defaulted to 5s for all commands executed, except:

• phpize - 1 minute
• ./configure - 2 minutes
• make - 10 minutes
• make install - 1 minute

I think these are reasonable maximums, but we can adjust accordingly with the constants defined going forward, should we need to.

make - 10 minutes

This seems short to me
Try ones of grpc, couchbase or datadog_trace on a slow computer (especially without -j option, see #73)

Would you be able to suggest a safer limit please?

No, IMHO, this should be unlimited
Even if quite confusing, especially because of no output by default.

For me, "stalled" means no output for a few minutes (build are usually very verbose), nothing related to the whole process duration.

Thanks - I've adjusted it to be unlimited in #76
