Subject: [PATCH] fix travis condition check

$travis may be undef after GetOptions("travis" => \$travis);
Will cause errors like this during build:

	Unknown option: installdirs
	Welcome to Alien::SDL2 module installation
	------------------------------------------
	checking operating system... MSWin32
	checking for gcc... yes
	checking build system type... MSWin32-x64-multi-thread
	checking platform specific module... using 'My::Builder::Windows'
	checking for config script... no
	checking for prebuilt binaries... yes, 1 option(s)
	Use of uninitialized value $travis in numeric eq (==) at Build.PL line 195.
