abseil-cpp: remove gentables binary from static lib

[haydenmc]

The current meson patch for abseil-cpp includes gaussian_distribution_gentables.cc as a source file for the abseil_random static library.

wrapdb/subprojects/packagefiles/abseil-cpp/meson.build

Lines 343 to 349 in f3628e2

	absl_random_sources = files(
	'absl/random/discrete_distribution.cc',
	'absl/random/gaussian_distribution.cc',
	'absl/random/internal/chi_square.cc',
	'absl/random/internal/gaussian_distribution_gentables.cc',
	'absl/random/internal/pool_urbg.cc',
	'absl/random/internal/randen.cc',

gaussian_distribution_gentables.cc has its own main() function, and is meant to be compiled into a separate binary used to codegen gaussian_distribution.cc, as indicated here. gaussian_distribution.cc is already committed to the abseil repo, so it does not need to be generated at build time.

Currently, if you use this wrap and statically link abseil_random from an executable, you will run into an issue where multiple main() functions are defined due to the inclusion of gaussian_distribution_gentables.cc.

This change removes gaussian_distribution_gentables.cc from the list of sources for abseil_random, resolving the issue.
