build: Automatically determine libgcrypt's file name.

* m4/guix.m4 (GUIX_LIBGCRYPT_LIBDIR): New macro.
* configure.ac: Use it when no --with-libgcrypt-* option was passed.
* README: Do not recommend --with-libgcrypt-prefix.

guix environment guix
- Re-run the 'configure' script passing it the option
'--with-libgcrypt-prefix=$HOME/.guix-profile/', as well as
'--localstatedir=/somewhere', where '/somewhere' is the 'localstatedir'
value of the currently installed Guix (failing to do that would lead the
new Guix to consider the store to be empty!).
