fix(exclude_platform): exclude PEP 600 manylinux tags

[LouisLau-art]

Fixes #830.

• Extend the linux platform patterns to match PEP 600 manylinux tags (manylinux_).
• Add a regression test to ensure manylinux_2_17_* wheels are excluded when linux is configured.

Test:

• .venv/bin/python -m pytest src/bandersnatch/tests/plugins/test_filename.py

Pull request overview

This PR updates the exclude_platform filter to better exclude Linux wheels by adding support for PEP 600-style manylinux tags, and adds a regression test to ensure the new tag format is filtered when linux is configured.

Changes:

• Extend Linux platform patterns to recognize PEP 600 manylinux tags.
• Reset ExcludePlatformFilter’s cached class-level pattern state in test setup to avoid intra-module test pollution.
• Add a regression test covering manylinux_2_17_* exclusion when linux is blocklisted.

The new PEP 600 pattern is "-manylinux_", which only matches when the tag is preceded by a hyphen. Wheel platform tags can be a dot-separated list (e.g. ...-manylinux2014_x86_64.manylinux_2_17_x86_64.whl), where a PEP 600 tag may be preceded by . instead. Consider also matching .manylinux_ (or parsing the wheel filename and matching only against the platform tag field) so PEP 600 tags are reliably excluded regardless of position.

	"-manylinux_", # PEP 600 (manylinux_<glibc-major>_<glibc-minor>_<arch>)
	"-manylinux_", # PEP 600 (manylinux_<glibc-major>_<glibc-minor>_<arch>) in hyphen-separated tags
	".manylinux_", # PEP 600 (manylinux_<glibc-major>_<glibc-minor>_<arch>) in dot-separated tags

ExcludePlatformFilter._patterns / _packagetypes are class-level caches. Resetting them in setUp() helps within this module, but the values will remain mutated after the last test and can leak into later test modules (causing initialize_plugin() to skip re-initialization). Consider also resetting these caches in tearDown() (or using addCleanup) to leave global state clean for the rest of the test suite.
