package/popt: fix build without wchar

Commit 82442b54b640fd4fbd5677e02690346a59f6cf13 removed
0001-no-wchar.patch but without importing an upstream patch that
"should" have been equivalent to our patch but resulted in a build
failure on toolchains with wchar but without mbsrtowcs

So add a bunch of upstream patches and a new patch to fix this build
failure

While at it, also put back 0003-glob-detection.patch which, again, has
been upstreamed but is not in version 1.18 ...
