libxcrypt: fix build with perl-5.38 and use master branch

* fixes do_configure failure:
  checking whether all ucontext.h functions are available... yes
  when is deprecated at libxcrypt/4.4.30-r0/git/build-aux/scripts/BuildCommon.pm line 522.
  Compilation failed in require at ../git/build-aux/scripts/expand-selected-hashes line 28.
  BEGIN failed--compilation aborted at ../git/build-aux/scripts/expand-selected-hashes line 28.
  configure: error: bad value 'all' for --enable-hashes
  NOTE: The following config.log files may provide further information.

* with this patch backported it works OK:
  libxcrypt/4.4.30-r0/git $ perl build-aux/scripts/expand-selected-hashes
  usage: expand-selected-hashes hashes.conf names,of,selected,hashes

* similarly do_compile failure:
  ../git/build-aux/scripts/move-if-change crypt-hashes.h.T crypt-hashes.h
  ../git/build-aux/scripts/move-if-change crypt-symbol-vers.h.T crypt-symbol-vers.h
  given is deprecated at ../git/build-aux/scripts/gen-crypt-h line 41.
  Makefile:3818: Makefile.deps: No such file or directory
  make: *** [Makefile:3715: crypt.h.stamp] Error 255

* also use master branch instead of develop, the SRCREV exists in both
  but stable metadata branches should track stable component branches

  libxcrypt/4.4.30-r0/git $ git branch -a --contains d7fe1ac04c326dba7e0440868889d1dccb41a175 | tee
  * develop
    remotes/origin/HEAD -> origin/develop
    remotes/origin/develop
    remotes/origin/master

  and oe-core master also uses master SRCBRANCH since:
