When using 'git-fetch' for the source, when a patch is applied part of
the version number is truncated.
The following derivations will be built:
/gnu/store/zsy0j8jfg4q4nz8xk5bpc3h5qrclm679-opencv-3.4.3-checkout.drv
/gnu/store/kadg4jnyar79mpz5bmmg4w3qgn0iy81r-opencv-3.4.tar.xz.drv

I guess the issue is in 'tarxz-name', defined within 'patch-and-repack':
(define (tarxz-name file-name)
;; Return a '.tar.xz' file name based on FILE-NAME.
(let ((base (if (numeric-extension? file-name)
original-file-name
(file-sans-extension file-name))))
(string-append base
(if (equal? (file-extension base) "tar")
".xz"
".tar.xz"))))
Unless the extension (everything after the last '.') of the original
file name is composed entirely of hexadecimal characters, it is removed.
In this case, I guess the extension is "3-checkout", so it's removed.
I'm reluctant to suggest a fix until I understand the rationale for this
behavior. It was added by Ludovic in February 2014, in commit
3ca00bb51e3ff906a700b6925e0ce81558c8c469.

packages: Support 'patches' and 'snippets' for sources that are directories.
* guix/packages.scm (patch-and-repack)[numeric-extension?, tarxz-name]:
New procedures.
[builder]: Adjust to deal with SOURCE when it's a directory.
<body>: Use 'tarxz-name'. Always add (guix build utils) to
IMPORTED-MODULES.
Do you remember why you decided to remove non-numeric extensions,
Ludovic?
Thanks,
Mark

I think the reason is that if the source directory is
/gnu/store/…-opencv-1.2.3, you want to keep it as is. IOW,
‘numeric-extension?’ is trying to determine whether the extension is
part of a version number.
Obviously it’s not working well in this case. :-)
I was thinking about using ‘package-name->name+version’ to improve the
heuristic but that doesn’t look very good either:
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (package-name->name+version "foo-1.2-checkout" #\-)
$7 = "foo-1.2"
$8 = "checkout"
--8<---------------cut here---------------end--------------->8---
Ludo’.
