3352da8da1243c03fc83ba678d2f5d193bd5a0c2 Add "export LC_ALL=C" to all shell scripts (practicalswift)

Pull request description:

  ~~Make sure `LC_ALL=C` is set when using `grep` range expressions.~~

  Make sure `LC_ALL=C` is set in all shell scripts.

  From the `grep(1)` documentation:

  > Within a bracket expression, a range expression consists of two characters separated by a hyphen. It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set. For example, in the default C locale, `[a-d]` is equivalent to `[abcd]`. Many  locales sort characters in dictionary order, and in these locales `[a-d]` is typically not equivalent to `[abcd]`; it might be equivalent to `[aBbCcDd]`, for example. To obtain the traditional interpretation of bracket expressions, you can use the C locale by setting the `LC_ALL` environment variable to the value C.

  Context: [Locale issue found when reviewing #13450](https://github.com/bitcoin/bitcoin/pull/13450/files#r194877736)
