guile: Leave 'scm_install_gmp_memory_functions' unchanged.

Browse source 
Since the switch to Guile 3.0.7 using mini-GMP, we can leave
'scm_install_gmp_memory_functions' to its default value, which is to use
custom memory allocators; there is no interference with users of GMP
such as GnuTLS/Nettle.

* gnu/packages/aux-files/guile-launcher.c (main) [!SCM_ENABLE_MINI_GMP]:
Leave 'scm_install_gmp_memory_functions' unchanged.
