[PATCH v2 06/11] t9903: move PS1 color code variable definitions to lib-bash.sh

[Richard Hansen <rhansen@bbn.com>]

Define a new 'set_ps1_format_vars' function in lib-bash.sh that sets
the c_red, c_green, c_lblue, and c_clear variables.  Call this
function from run_pcmode_tests().  This is a step toward moving the
shell prompt tests to a separate library file so that they can be
reused to test prompting in Zsh.
