Description of problem:
genhomedircon doesn't strip the newline when constructing VALID_SHELLS thus
VALID_SHELLS looks like this:

['/bin/sh\n', '/bin/bash\n', '/sbin/nologin\n', '/bin/tcsh\n', '/bin/csh\n',
'/bin/ksh\n', '/bin/zsh\n']

This then goes on to fail the shells of users who have this:
'/bin/bash'

Version-Release number of selected component (if applicable):
policycoreutils-1.30.10-1.fc5

How reproducible:
Every time

Steps to Reproduce:
1. Add print VALID_SHELLS beneath line 33
2. Run /usr/sbin/genhomedircon
3. (For extra hilarity run "/sbin/restorecon -R -v /home" on a system with user
home dirs that are in subdirectories e.g. /home/member/user )
  
Actual results:
['/bin/sh\n', '/bin/bash\n', '/sbin/nologin\n', '/bin/tcsh\n', '/bin/csh\n',
'/bin/ksh\n', '/bin/zsh\n']

(in the extra hilarity case parts of a user's home directory become mislabelled
e.g. public_html)

Expected results:
same output as above but without the newline (\n) characters

Additional info:
Fixable by changing the VALID_SHELLS line to:
VALID_SHELLS = fd.readlines().trim()
Python documentation warns that the newline isn't stripped here:
http://docs.python.org/lib/bltin-file-objects.html#l2h-244

Setting to severity to high because of the breakage caused on a relabel.
