adapt_cmakelists_file: quote the metacharacters

Summary:
When used in patterns, apparently metacharacters must be properly
quoted or the interpreter returns an error in newer version of Perl
(tested with 5.26).
In fact the metacharacters were already quoted in some patterns.

Test Plan: Tested live when porting kimagemapeditor.
