João Barbosa f652f85d0c qa: Ignore shellcheck warning SC2236
With shellcheck 0.6.0 the warning `SC2236 -  Use -n instead of ! -z` is raised.
This change adds that warning to the ignored list.

# Disabled warnings:
# SC1087: Use braces when expanding arrays, e.g. ${array[idx]} (or ${var}[.. to quiet).
# SC1117: Backslash is literal in "\.". Prefer explicit escaping: "\\.".
# SC2001: See if you can use ${variable//search/replace} instead.
# SC2004: $/${} is unnecessary on arithmetic variables.
# SC2005: Useless echo? Instead of 'echo $(cmd)', just use 'cmd'.
# SC2006: Use $(..) instead of legacy `..`.
# SC2016: Expressions don't expand in single quotes, use double quotes for that.
# SC2028: echo won't expand escape sequences. Consider printf.
# SC2046: Quote this to prevent word splitting.
# SC2048: Use "$@" (with quotes) to prevent whitespace problems.
# SC2066: Since you double quoted this, it will not word split, and the loop will only run once.
# SC2086: Double quote to prevent globbing and word splitting.
# SC2116: Useless echo? Instead of 'cmd $(echo foo)', just use 'cmd foo'.
# SC2148: Tips depend on target shell and yours is unknown. Add a shebang.
# SC2162: read without -r will mangle backslashes.
# SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
# SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined.
# SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?.
# SC2206: Quote to prevent word splitting, or split robustly with mapfile or read -a.
# SC2207: Prefer mapfile or read -a to split command output (or quote to avoid splitting).
# SC2230: which is non-standard. Use builtin 'command -v' instead.
# SC2236: Don't force -n instead of ! -z.
