Patch does not work for packages that don't immediately cd into the source directory

For example, the package kdeplasma-applets-menubar-archway-bzr:

# ...
build() {
  [ -f build ] && rm build
  [ -d build ] || mkdir build
  cd build
  cmake ../$pkgname \
# ...

After running customizepkg:

build() {
  [ -f build ] && rm build
patch -Np1 -i remove_right_icon.diff
  [ -d build ] || mkdir build
  cd build

And then patch breaks, because the diff expects to be in build/, where the source code is.

I have a possible fix for this in my branch, evaryont@9fb3ee5 but it's pretty dirty.

I believe for such PKGBUILD replace can be used to insert the patch string to the correct location, so I think we can live with this patch command limitation.

Or, for anyone else that might stumble upon this, they could also use the newly added addline action as well.
