[BUG] Verilator linting include paths broken on v1.11.7

[darrylring]

This change breaks Verilator linting (at least with Verilator 5.010 on Linux).

It adds double quotes to the include paths passed to Verilator, but also adds a space between -I and the quoted path. Verilator interprets these paths as module names instead of include paths.

As a simple test:

$ cat test.v
module test;
endmodule

$ verilator --lint-only -I/tmp test.v
$ echo $?
0

$ verilator --lint-only -I /tmp test.v
