Sync golang-1.19 1.19.6-1 (main) from Debian unstable (main)

[Shengjing Zhu]

Please sync golang-1.19 1.19.5-1 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
- 0001-cmd-link-check-CGO_CFLAGS-for-non-g-I-O-options-befo.patch
  disable internal linking when dynamically linking and CGO_CFLAGS
  contains flags that might make host object files that the internal
  linkers ELF reader does not support. This fixes lots of package builds
  when LTO is enabled by default via dpkg-buildflags.

  This is fixed in dpkg and dh-golang. See LP#2002076 and LP#2002201.
  So it's obsoleted in Ubuntu.

- d/rules: Add NO_PNG_PKG_MANGLE to prevent a test file from being
  compressed.

  This is applied in 1.19.5-1 in Debian.

Changelog entries since current lunar version 1.19.4-1ubuntu1:

golang-1.19 (1.19.5-1) unstable; urgency=medium

  * Team upload
  * Add NO_PNG_PKG_MANGLE to prevent mangling testdata.
    This is Ubuntu specific behaviour so they can sync the package without
    vendor patch.
  * New upstream version 1.19.5
