[compiler-rt][test] Rewrote test to fix usage of export with 2 arguments

[connieyzhu]

This patch fixes the incorrect usage of lit's built-in export command in this compiler-rt test. The export command only allows for one argument, but %env_asan_opts expands to "env ASAN_OPTIONS", which gives export two arguments instead of only one. Instead of using export, which propogates the environment variable value to all subsequent commands, the environment variable is manually set before all RUN lines following the original export line.

This patch depends on #105961.

Fixes #106142.
