Đoàn Trần Công Danh be5369a0cb srcpkgs/f*: convert patches to -Np1
* fpc is kept at -Np0

```sh
git grep -l '^patch_args=-Np0' "srcpkgs/$1*/template" |
while read template; do
	for p in ${template%/template}/patches/*; do
		sed -i '
			\,^[+-][+-][+-] /dev/null,b
			/^[*-]\+ [0-9]\+\(,[0-9]\+\)\? [*-]\+$/b
			s,^[*][*][*] ,&a/,
			/^--- /{

CompositableHost.cpp patch added by @q66, based on patch in issue 1602730.

Problem description: Tab-titles that are too long to fit into a tab get faded out.
On big endian this is broken and instead of fading out, the
tab gets white and the font transparent, leading to an unreadable
tab-title
Solution: This is not a real solution, but a hack. The real solution would have been
to byte-swap the correct buffer, but I could not find it.
So the next best thing is to deactivate the fading-effect. Now all tab-titles
are readable, albeit not as pretty to look at as they could be.
Side-effects: I have not yet found an unwanted side-effect.
