erlang: fix PKG_CPE_ID escaping for apk ADB format

apk's ADB binary package format rejects both the backslash-escape and
the percent-encoding variants of the previous CPE id:

  cpe:/a:erlang:erlang\/otp     ERROR: info field 'tags' has invalid value
  cpe:/a:erlang:erlang%2Fotp    ERROR: info field 'tags' has invalid value

apk's tag value parser only accepts a restricted alphabet for ADB
package format and neither '\' nor '%' make the cut. The result is
that the package never produces an .apk.

Drop the '/otp' suffix entirely and use cpe:/a:erlang:erlang, which
matches the higher-level Erlang CPE entry. cve scanners that walked
the more specific erlang\/otp entry will fall back to this one.

This effectively reverts the product portion of bfdf01496 ("lang/erlang:
fix PKG_CPE_ID"), which was correct against the NIST 2.3 string but
incompatible with apk's tag parser.
