Subject: [rubygems/rubygems] Fix test_install_location_extra_slash on alpine

Under POSIX behavior of leading // is implementation defined. Musl does
preserve it in realpath, glibc does not. That means the test was failing
when executed on alpine linux. Original issue #508 was about // in the
path, not about leading ones. When executed in such environment, the
test will still test what it should when the explicit mangling of the
path is not done.

Fixes #5652
