So I am writing a book on Awk programming language, and I have enabled a single frame via \lstset{frame=single}. However, I would like the code within the snippet box to be further away from the frame border. Any ideas how to change the padding of the code within the snippet box? In HTML I'd just do padding: 5px, but I can't figure out how to do it in LaTeX.

Use a sensible fontencoding. And make a complete example next time so that nobody has to guess what you are doing wrong.
\documentclass{article}
\usepackage{listings}
\usepackage[T1]{fontenc}
\begin{document}
\begin{lstlisting}
"a"
\end{lstlisting}
\end{document}
Btw: Don't rely to much on copying code from a pdf. Spaces can disappear.
The background color and the frame are drawn for every line separately. listings assumes a certain line height and such graphic errors appear if the real height is larger than that. From your image I would guess you are using a larger font for the line numbers than for the normal text. You should set numberstyle to the same or smaller size than the normal text.
In my test I get the same white lines if the numberstyle is larger than the basicstyle (left) but not if it is smaller (right) or the same size.
\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}
\begin{document}
\begin{minipage}{.2\textwidth}
\begin{lstlisting}[basicstyle=\scriptsize,numberstyle=\large,backgroundcolor=\color{black!20},numbers=left,frame=lrtb]

Found it myself, it's
\lstset{framesep=10pt}and as przemoc suggests in the comments also do\lstset{xleftmargin=10pt,xrightmargin=10pt}to make sure margins don't go outside of margin space.
