cygprofile: increase timeouts to allow showing web contents

cygprofile: increase timeouts to allow showing web contents

Also doing a fork() changes thread id (syscall gettid), which breaks the
assumptions in cygprofile.cc, disabled a fork in library_prefetcher.

Verified: with these changes the instrumented build is able to display the
contents of 'https://google.com'. It does not finish loading though, which is
probably due to some other timeouts.
