Log Message:
Updated pkglint to 5.4.11.

Changes since 5.4.10:

* Replaced regular expression with hand-written matching code, since
  it is 30 times as fast.
* Reduced number of syscalls by remembering os.Lstat results and
  CVS/Entries.
* Reduced number of syscalls by querying the current user only once.
* Added warning for comparing ${PKGSRC_COMPILER} == "clang", which
  should rather be ${PKGSRC_COMPILER:Mclang}.
* Added variable definitions for NOT_PAX_ASLR_SAFE and NOT_PAX_MPROTECT_SAFE.
