IMPALA-14530: Limit link concurrency with flock
Adds a wrapper around 'gold' that limits concurrency using 'flock'.
Concurrency is limited to IMPALA_LINK_THREADS by using a pool of link
files and randomly selecting from them.
Uses 'ld.gold' to select the version in binutils, and '--threads' to use
more cores while still limiting memory from multiple links.
New link option is selected by setting IMPALA_LINKER=fold, which is now
set as the default. Performance does not appear to be significantly
worse than before, and link actually succeeds on rebuild dominated by
linking test binaries.
Adds MOLD_JOBS=1 to avoid overloading the system when trying 'mold' and
linking test binaries. However 'mold' is not selected as the default
due to test failures around SASL/GSSAPI.
Removes the guard in bootstrap_development.sh limiting
IMPALA_BUILD_THREADS as it's no longer needed with default config.
