rule accounts_tmout is misaligned with DISA STIG

[vojtapolasek]

Description of problem:

The problem is with the rule account_tmout.
This rule checks for certain line within Bash startup files.
The DISA counterpart is xccdf_mil.disa.stig_rule_SV-204579r861070_rule.
The core of the problem lies in the fact that DISA uses the "declare" keyword in the command, where our content has recently switched to usage of "typeset". It happened in this PR: #11289
It increases compatibility with shells.

SCAP Security Guide Version:

stabilization-v0.1.72 branch, commit 7fb44f7

Operating System Version:

RHEL 7

Steps to Reproduce:

1. scan and remediate system with our content, then scan again and save results
2. scan the system with DISA SCAP and save results
3. use the compare_results.py script to compare result files and see difference.

Alternatively, build the datastream and search for "tmout" in OVAL. Do the same for the DISA provided SCAP file.

Actual Results:

While the rule from this repo passes, DISA content rule fails.

Expected Results:

Both rules should pass.
