panic when specifying multiple excludeFiles directives

[stapelberg]

Thank you @bep for adding excludeFiles in 471ed91

The directive seems to work fine when using a single excludeFiles string value:

[module]
[[module.mounts]]
  source = 'static'
  target = 'static'
  excludeFiles = "turbopfor/*[^s][^v][^g][^o].svg"

But when I want to add another exclude pattern, hugo panics:

[module]
[[module.mounts]]
  source = 'static'
  target = 'static'
  excludeFiles = ["turbopfor/*[^s][^v][^g][^o].svg", "turbopfor/Makefile"]

Thanks for that report, I willl fix -- I kind of just assumed that it would work.
