package/libkcapi: bump version to latest git hash 79cb80714ebc

Configure script is used to detect options supported by the target
compiler, but those options are then incorrectly used by the targets
compiled using a host compiler.

configure:
  checking whether CC supports -fstack-protector-strong... yes
make:
  /usr/bin/gcc (...)
  cc1: error: unrecognized command line option "-fstack-protector-strong"
