guix: increase maximum allowed (runtime) GCC to 7

fanquake commented at 1:48 pm on August 12, 2025: member

Fixes:

0/distsrc-base/distsrc-d3b8a54a8120-x86_64-linux-gnu/build/bin/bitcoind: symbol __divmodti4 from unsupported version GCC_7.0.0(14)
1/distsrc-base/distsrc-d3b8a54a8120-x86_64-linux-gnu/build/bin/bitcoind: failed IMPORTED_SYMBOLS

which is occuring after #32750. I can’t see any supported distro that is shipping a new enough glibc (2.31), but a GCC older than 7.0.

Fixes #33177.

Makes sense, GCC 7 is from 2017, Glibc 2.31 is from 2020.
