build: Fix libgcrypt detection on FHS systems.

Browse source 
Reported by Christopher Allan Webber <cwebber@dustycloud.org>.

* m4/guix.m4 (GUIX_LIBGCRYPT_LIBDIR): Add "grep -e -L" to the pipeline
  to account for cases where the output of "libgcrypt-config --libs"
  lacks a -L flag.
* configure.ac: When 'GUIX_LIBGCRYPT_LIBDIR' returns the empty string,
  set LIBGCRYPT_LIBDIR to "no".
* config-daemon.ac: Add missing space.
