linpeas: Broken scan for problems in SUID programs

[kgraefe]

If you are going to suggest something, please remove the following template.

Issue description

When scanning SUID programs on my system none of the "It looks like" suggestions were printed although I know there are at least some.

Steps to reproduce the issue

Run ./linpeas.sh -o IntFiles

Which parameters did you use for executing the script and how did you execute it?

-o IntFiles

Is there any AV / Threat protection in the system?

no

Please, indicate the OS, the OS version, and the kernel version (build number in case of Windows)

Custom Linux distribution based on Yocto/busybox with customized Linux kernel 5.10.47-rt46.

Please, indicate the check that is failing and add a screenshot showing the problem

How did you expect it to work?

Additional details / screenshot

• The quotes in linpeas_base.sh#L2560 should not be escaped. $sline_first becomes e.g. "cat" where it should be cat. This is broken since https://github.com/carlospolop/PEASS-ng/commit/fbe0004755b9cf1df19778bc6986cd361889a331
• On my machine grep -qv ".." in linpeas_base.sh#L2567 matches any characters, basically disabling printf completely. The dots should be escaped. This is broken since https://github.com/carlospolop/PEASS-ng/commit/883e5b56e6c9fe4708039d963649fb554c5bf63e .
