Does not compile with glibc 2.34

[chubin]

I am trying to compile stduuid with Glibc 2.34 but it does not seem to work:

The problem is that in glibc 2.34, MINSIGSTKSZ is no longer a constant

[mariusbancila]

This was a problem due to Catch2 using MINSIGSTKSZ. See: catchorg/Catch2#2178.

I have updated the Catch2 version. The problem should be fixed now.
