Comment (by gxm):

 It was may post on The Tor Blog reporting of the issue. I confirm that
 torbrowser 7.0.1 works normally in CentOS 6.5 chroot environment (as well
 as 7.5a) after mounting shm filesystem. To summarize the dependences, they
 are listed as follows. May be it would be helpful for somebody.

 1. Unpacked installation directory of torbrowser
 2. Shared libraries that torbrowser executables and libraries depend from
 3. Appropriate configuration files
 4. Unix socket for X server
 5. Device files: null, random, urandom
 6. Filesystems: proc, shm (mount their directories with option --bind)

 It's strange that torbrowser can connect to HTTPS sites without device
 files random and urandom (where it takes the enthropy from?), however it
 writes warnings in the terminal window. Contrary to this, tor daemon,
 chrooted seperately, doesn't work without these files.
